The hits keep on coming for Conor McGregor -- this time, it's Floyd Mayweather trashing his old boxing opponent ... "Con Artist McLoser."

In fact, Floyd says the positive way Conor continues to be treated by the public even after multiple losses -- while Mayweather still gets constant hate -- is proof racism is still alive and well.

"The world knows Con Artist McLoser can steal everything from me and be loved but I’m hated," Mayweather posted on IG after Conor got knocked out by Dustin Poirier at UFC 257.

"That just lets you all know that racism still exist."

Remember, Floyd beat up Conor in their 2017 boxing match -- dominating from start to finish ... with the ref stopping the fight in the 10th round.

Then Floyd really dug and unloaded on Conor ... suggesting Conor also ruined his shot at a high-profile boxing match with Manny Pacquiao.

"Just know, that bum will never be me or be on my level. I’m just built different, my mindset is on another planet, my skills are second to none, I’m a natural born winner and yes I talk a lot of trash, but every time I back it up!"

"This is what they hate. It’s sad that you can be a poor black kid from the ghetto that has dealt with racism your whole life and work extremely hard to put yourself and your family in a better position, and most of the hate come from my own people."

"Connor [sic] cannot even win in his own sport, but talking about coming back to boxing to fight Pacquiao. Nobody wants to see that, it's like my leftovers eating leftovers."

So, what now for Conor? He's gunning for a rematch with Dustin Poirier ... and Khabib Nurmagomedov ... and also Floyd.

DUSTIN POIRIER!!!!!

The Diamond just KNOCKED OUT Conor McGregor at UFC 257 -- and man, was that violent!!!!

McGregor seemed to be in control in Round 1 -- but Dustin took over in Round 2, obliterating McGregor with a series of shots before ending it with a strong right hook that sent Conor right to the mat.

Dustin avenged his 1st round loss to Conor when they fought in 2014 -- a fight Dustin has wanted to run back for years!!

Dustin's game plan was obvious -- he targeted Conor's legs hoping to wear the guy down ... and he did just that.

After the fight, Dustin called a 3rd fight with Conor -- and bragged he's the best boxer in the UFC.

Conor was respectful after the fight -- and offered an explanation for the loss.

"I just wasn't as comfortable as I needed to be," Conor said after the fight ... insisting he's been out of the Octagon too long to compete with the best in the world.

It was McGregor's first fight since January 2020 -- when he defeated Cowboy Cerrone in a 1st round knockout.

Before that, Conor got beat up by Khabib Nurmagomedov at UFC 229 in October 2018. He hadn't fought before that since Nov. 2016.

Here's the bottom line for Conor -- it would be hard for Khabib to be impressed enough by Conor's performance to warrant a rematch.

In fact, Khabib sent a tweet seemingly aimed at Conor after the fight -- basically saying Conor has strayed from what made him great.

"This is what happened, when you change your team, leave the sparring partners who made you a champion and sparring with little kids, far away from reality."

Conor McGregor is getting ready to enter the UFC Octagon in what promises to be one of the biggest fights ever ... and he could draw some inspiration from this kid, who clearly drew inspiration from Conor.

Brice Gonzalez is amazing. The 5-year-old, with the help of his dad Randy, mimicked Conor after an earlier, 1st round K.O. against Dustin Poirier. The kid's attitude is spot on, and he's exceptional at memorizing his lines.

Randy has created a hugely successful comedy show with his son, which gets millions of views on social media. Randy, who served time in prison, was having a hard time finding a job. Then he came up with the idea of a comedy show, and it exploded.

Randy and Brice have gained a bunch of celeb followers, including Kevin Hart and Snoop.

The UFC just fired one of its top rising stars -- undefeated Ottman Azaitar -- after he allegedly committed one of the most INSANE safety violations we've ever heard.

Ottman -- who's 13-0 as a pro with some crazy highlight-reel knockouts -- allegedly stole a page out of a "Mission Impossible" movie to sneak an unapproved guest into the Fight Island area on Abu Dhabi, risking the health of EVERYONE there.

FYI, 30-year-old Ottman was scheduled to fight on the main card at "UFC 257: Poirier vs. McGregor" on Saturday night -- taking on 30-year-old Matt Frevola (8-1-1).

But, that fight was removed from the card on Friday due to a "health and safety violation."

So, what the hell happened?! Dana White explained to BT Sport ... and man, the allegation is bad.

"So [Ottman Azaitar] and his team cut off their wrist bands, gave 'em to somebody outside the bubble," White explained ... "I don't know how they even did it."

"That guy taped [the wristbands], showed up here [on Fight Island] with a bag, went into a room, shimmied across 4 balconies, went in [Ottman's] room, dropped the bag off, changed his clothes and then left."

WHAT?!!??!?!

Dana continues ...

"Now, when security tried to stop him, he wouldn't stop either way and yeah it's just bad."

Dana said he fired Ottman on the spot -- "He's gone. He's no longer a UFC fighter and he's not fighting [Saturday night]."

Wow.

The big question -- what was inside the mystery bag?!!?!? Our UFC sources say they have no clue at the moment. Guessing they're going to try and find out.

As we previously reported, the Fight Island area is incredibly secure -- with multiple COVID testing points and crazy security to keep everyone safe. One violation could compromise the entire thing.

Conor McGregor has big plans after UFC 257 -- most notably, he badly wants a rematch with lightweight champion Khabib Nurmagomedov.

So, what happens if he loses to Dustin Poirier on Fight Island this weekend? That's the question we posed to Dana White.

"Nothing happens," Dana said ... "People lose man. It happens. It’s part of the sport."

"If he loses, he goes back to the drawing board and comes back and fights another day."

Sure, but who gets the next title shot?

Dana says it's pretty obvious Poirier will gun for a rematch with Khabib if he wins -- but nothing's guaranteed, considering all of the monsters fighting for control of the UFC's stacked lightweight division.

"Charles Olivera (ranked #3) just came off an incredible win over Tony Ferguson (#5). You got Poirier (#2) and McGregor (#4) fighting on Saturday and the co-main event is #6 ranked Dan Hooker vs Michael Chandler, who is making his debut in the UFC. This guy has been fighting everywhere outside of the UFC and is one of the all-time greats in the division. He wants to prove himself now in the UFC."

"So, any one of these guys could end up fighting Khabib."

Conor McGregor has broken his silence about the multi-million dollar lawsuit filed against him by a woman in Ireland ... claiming he's already been "cleared of all wrongdoing."

The UFC fighter is being sued over an alleged incident that took place on Dec. 9, 2018. The New York Times reports the woman is the same person who accused McGregor of rape.

In fact, the NYT says the woman's allegations involve claims she was roughed up and raped by the UFC star at a hotel penthouse in Dublin.

According to the NYT, the woman claims she rejected McGregor's sexual advances -- but he continued to kiss her and remove her clothes. The woman claims she bit and hit Conor in an attempt to fight him off -- but he grabbed her around the neck and lifted her up 3 times until she stopped resisting.

The next morning, McGregor's friend told her the UFC star had sex with her, the accuser claims. She was later examined in a sexual assault treatment at a hospital and went to the police the following month.

News of the suit being filed broke just days before McGregor's January 23 return to the Octagon to take on Dustin Poirier on Fight Island at UFC 257.

McGregor was asked about the allegations during the UFC pre-fight press conference on Thursday morning --  and defended himself vigorously.

"It's old news," McGregor said of the allegations ... "It was investigated thoroughly over the course of 2 long years and I was cleared of all wrongdoing."

McGregor then changed the subject and focused on his fight against Poirier.

As we previously reported, Conor's rep issued a statement denying the allegations ... explaining, "After an exhaustive investigation conducted by the Garda which, in addition to interviews of the plaintiff, included: interviewing numerous sources, obtaining witnesses' statements, examining closed-circuit footage and the cooperation of Conor McGregor, these allegations were categorically rejected."

"The plaintiff knows the facts contradict the assertions in this lawsuit. Mr. McGregor will dispute any claims and is confident that justice will prevail."

As for the rest of the UFC 257 presser, Conor and Dustin were respectful -- and praised each other a lot. The fought back in 2014 and Conor won in just under 2 minutes into the 1st round.

Michael Chandler is making his UFC debut this weekend after years of kicking ass in Bellator ... and the MMA star says he's gunning to give Khabib something "spectacular" -- and entice the retired lightweight champ back to the Octagon.

TMZ Sports talked to 34-year-old Chandler from Abu Dhabi ... and asked about his "dream scenario" -- is it a Conor or Khabib fight??

"I came [to the UFC] for big fights, of course, but I also came here, I want that gold around my waist. Having the gold around your waist, in turn, gets you the bigger fights," Chandler tells us.

And, the guy with the title ... that's Nurmagomedov.

"I would have to say if I had to lean one way, I would go Khabib. You gotta get that title shot. Those are not easy to come by here in the UFC, so I would definitely choose that, but of course they’re all getting talked about after I win my fight Saturday night."

Chandler -- whose beaten guys like Eddie Alvarez and Benson Henderson (twice) -- takes on #6 ranked lightweight, Dan Hooker (wins over Paul Felder, Gilbert Burns) on Fight Island.

Of course, Dana White recently met with Khabib on Fight island ... and said the 29-0 fighter was looking for something "spectacular" from Conor, Poirier, Hooker or Chandler -- in order to consider returning to fight.

"'Spectacular' is always my main objective when I step inside of that cage, and that cage door closes. It's time to work, and I'm always looking for the finish," Chandler says.

From there ... Michael would like to fight Khabib, take his belt, and then book a fight with McGregor.

Conor McGregor Jr. is already learning the ropes of being super famous ... joining his papa for an incredibly adorable poster signing sesh ahead of UFC 257!!!

3-year-old Conor Jr. has pretty much been following in his MMA superstar dad's footsteps since birth -- from joining him in the gym to wearing stylish designer outfits together.

Conor decided to bring his mini-me along to sign some promo posters ahead of his huge Fight Island bout with Dustin Poirier ... and the kid didn't just sit around -- he got in on the action, too!!

The video is downright precious ... with Notorious walking Conor Jr. through the motions and showing him how to get through the sesh with ease.

Conor absolutely LOVES it ... laughing and smiling from ear-to-ear as his kid signs to the best of his ability.

Now, the big question is -- how much would a Conor McGregor JUNIOR autograph sell for?? Hard to tell, but these posters could very well be the first documented signature of the young boy's life.

FYI -- signed Conor pics ain't cheap. Most cost a couple hundred dollars.

Two women in Ireland are suing Conor McGregor stemming from alleged incidents in 2018 ... but the UFC superstar is ADAMANT he did nothing wrong.

The suits were filed Monday in Dublin, according to Independent.ie, with one woman lodging a "multi-million euro personal injury lawsuit."

The other suit, the report notes, was filed by the woman's mother ... and also appears to be for alleged personal injuries.

Specific allegations against McGregor in the suits are not yet public ... according to the report, details cannot be revealed yet for legal reasons.

But, 32-year-old Conor is calling B.S. on it all nonetheless, with a rep for the fighter telling TMZ Sports the matter has already been investigated and thrown out by law enforcement officials.

"After an exhaustive investigation conducted by the Garda which, in addition to interviews of the plaintiff, included: interviewing numerous sources, obtaining witnesses' statements, examining closed-circuit footage and the cooperation of Conor McGregor, these allegations were categorically rejected," Karen J. Kessler said in a statement.

"The plaintiff knows the facts contradict the assertions in this lawsuit. Mr. McGregor will dispute any claims and is confident that justice will prevail."

Calvin Kattar says his UFC on ABC main event match with Max Holloway is more than just a fight ... a win represents a better life -- more money, more opportunities.

TMZ Sports talked to the 32-year-old fighter before his Fight Island fight this weekend with the former featherweight champ ... and Kattar says only everything is on the line.

"I ain't got s*** to say to Max! I'm just going out looking to earn my respect and just get me a title shot, ya know? Change my life."

"I'm chasing the life on the other side of a win over Max Holloway. Things get better off wins, you get double the money, you get more opportunities and like I said, I'm just chasing the life off a win over Max Holloway."

Kattar -- the #6 ranked featherweight -- is 22-4 ... and coming off wins over Jeremy Stephens and Dan Ige.

Calvin's been super impressive ... but things don't get any easier on Fight Island ... 'cause Holloway is arguably the greatest 145 lb.'er of all-time.

As for blessed, he's looking to claw his way back to the top of the UFC mountain after 2 controversial losses to Alex Volkanovski ... and that's exactly what he tells us he'll do.

"Belt or no belt, I'm gonna always carry myself as a champion. The belt doesn't define me. I got 5 titles at home. The 6th, 7th, 8th, 9th, 10th, all the way to 13, 20, whatever you wanna call it, I'm gonna get it. It's just in due time," Max tells us.

Cody Garbrandt has a plan ... fight Jose Aldo, beat Aldo, drop down a weight class and take on the winner of Deiveson Figueiredo and Brandon Moreno ... and get the UFC belt back!

The 29-year-old former bantamweight champ is coming off a serious battle with COVID-19 (more on that later) ... and hasn't fought since knocking out Raphael Assuncao in June 2020.

But, No Love is back ... and he laid out his next moves to TMZ Sports.

"The best possible solution for me in my mind, is the Aldo fight. So I'm gonna keep my weight here, keep strong, keep fast, keep developing, ya know?"

Garbrandt is the 3rd-ranked 135 lb. fighter ... and 34-year-old Aldo is 6th -- but Cody knows the Brazilian legend is still very dangerous.

"[Aldo's] a long-standing rival with Team Alpha Male, but can always count on me. Count me to get the job done, and I'm focused, and I'm hungry and that's where I'm at in my career and in my life. I'm a dangerous man."

After beating Aldo, Cody tells us he plans to drop down to the 125 lb. division and take on the winner of the Figueiredo and Moreno rematch.

"I'll fight Aldo in April. Put a legend in my cap. Get a good win, fight a legend. Stay sharp at camp and then whoever wins out of that fight with Figgy and Moreno, we fight in September or August."

Garbrandt also breaks down his serious struggles with COVID ... and how he dealt with vertigo, pneumonia, and a kidney infection that hospitalized him.

A magnesium globe? Check. A one-of-a-kind diamond? Check. A four-satellite structure that moves at a crazy speed set on a base of diamonds that's encased in crystal and gold? Check!

Yup, Conor McGregor's new wristwatch has it all ... the UFC fighter flaunted the newest addition to his wardrobe Thursday -- and it's INSANE!!!

The piece is called Astronomia Tourbillon Baguette ... and it's reportedly valued at over $1 MILLION.

The folks at Jacob & Co. created the piece -- and it's clearly so cool, Conor just had to cop it before his huge fight with Dustin Poirier at UFC 257 next weekend.

McGregor bragged about the watch on social media, posting pics and videos with it -- and he even said he got a new pricey car and suit to go along with it.

Jacob & Co. reps say the watch is truly an epic piece ... and in the video they created to show the thing off -- you can see just how intricate and amazing the flashy mechanism is.

Of course, McGregor is no stranger to fancy watches (he's copped this one AND this one just recently) ... but when you're the Notorious One, you can never have too many options, right??

UFC fighter Irwin Rivera has been arrested for 2 counts of attempted murder ... according to a jail official.

31-year-old Rivera is a UFC bantamweight (135 lbs.) fighter who first fought with the promotion in May 2020. Rivera is 1-2 in the UFC ... and 10-6 as a professional.

Rivera was booked into the Main Detention Center in West Palm Beach, FL around noon on Thursday, per jail online booking information.

The UFC issued a statement on Rivera's arrest, saying ... “UFC is aware of the recent incident involving Irwin Rivera and subsequently received information from his management that he has been exhibiting behavior consistent with mental health issues.”

The statement continues ... “The allegations are extremely troubling and the organization is currently gathering additional information. The investigation is ongoing and any potential next steps including disciplinary action or medical attention will be determined upon the conclusion."

"Furthermore, UFC has informed Rivera’s management that he will not be offered a bout at this time.”

Before his arrest, Rivera was originally scheduled to fight at UFC Fight Night in March.

UFC fighter Mike Perry is on the mend after slicing himself open during a bizarre incident late Sunday night -- posting footage showing doctors stitching up his wound.

The 29-year-old initially posted video showing him lying in a pool of blood Sunday next to a shattered glass door. It appears as if Perry opened a massive gash while trying to smash through the glass.

While on the ground, Perry says to himself, "F*ck am I supposed to do about this?"

Fans on social media expressed concern for the fighter who seems to be in a downward spiral -- following allegations of domestic abuse and a separate violent incident at a steak restaurant back in July.

But, early Monday morning, Perry posted video from what appears to be a hospital room -- showing a doctor treating the wound on his lower right leg.

A few hours later, Perry posted more footage showing himself walking his dog -- so, all better?

Perry has fought in the UFC since 2016 and has flashed real potential -- earning multiple fight of the night and performance of the night bonuses along the way.

But, losses to guys like Cowboy Cerrone, Geoff Neal and most recently Tim Means (in Nov.) have kept him from reaching that next level.

MMA star Anthony Pettis says that he's 100 percent down to fight Jake Paul ... and he's willing to do it in the boxing ring -- a place where he has no experience.

But, Jake does -- he's 2-0 as a professional boxer.

TMZ Sports talked to the 33-year-old fighter before his unanimous decision UFC Fight Night win over Alex Morono in Vegas ... and Pettis was crystal clear -- he wants to box before he retires, and Jake Paul would make for a helluva opponent.

"Bro, I would love to box. I haven't boxed yet, so I'm 0-0. Boxing is something I grew up watching my whole life. That's why I got into fighting, honestly. Watching Chavez, De La Hoya, Mayweather, all these guys up and coming."

Of course, Paul knocked former NBA star Nate Robinson out cold over a month ago. There's been debate about how good JP actually is in the squared circle ... but Pettis believes Jake has skills.

"I think he's definitely getting better. He prepared for a boxing match. You could tell he was in boxing shape, he was in a stance at least. It's going to be interesting to see how far he can go with it."

Even if it's not against Jake Paul, Pettis -- a former UFC champ with wins over guys like "Cowboy" Cerrone and "Wonderboy" Thompson -- says he's gonna give boxing a shot before he retires from fighting.

"Man, I'm only 33, and I've been doing this MMA thing for so long. 12 years with Zuffa. So as a pro, I think I've been like 14 years. It's a crazy life I live. I'd love to go in there and try something new," Pettis tells us.

Bottom line ... "I definitely think before I retire boxing will be something I do."

Khabib Nurmagomedov is adamant he's retired, but there's one guy his manager says could entice the UFC superstar to step back in the Octagon ... a fight with Georges St-Pierre!!

TMZ Sports talked to Ali Abdelaziz ... and we straight-up asked Nurmagomedov's longtime manager and friend if he believes Khabib will fight in 2021.

"Honestly, I think if Georges St-Pierre is serious about coming back to fight, I could see it happening, that would get Khabib up."

The issue ... St-Pierre is 39-years-old and hasn't fought since beating Michael Bisping in 2017. In fact, GSP has only fought since the end of 2013.

Khabib's father, Abdulmanap -- who passed away from COVID-19 complications in July -- always wanted his son to fight GSP.

If not GSP, are there any other fights Abdelaziz believes would intrigue Khabib enough to return ... say like a HUGE money fight against Conor McGregor?

Very unlikely, according to Ali.

"I think financially it’s a huge fight. But, we know Khabib, it’s hard to persuade him financially."

Abdelaziz tells us Khabib and Dana White are planning to sit down for dinner in Vegas sometime soon ... and discuss Khabib's fighting future.

And like Ali says, "Dana is really good at getting people to do things."

So ... Khabib vs. GSP, 2021??
