Boxing

Floyd Mayweather or Manny Pacquiao?

Tito Ortiz says it doesn't matter ... 'cause Conor McGregor would get his ass kicked by either guy in a boxing match.

The Huntington Beach Bad Boy was at ArcLight Hollywood for the "John Wick: Chapter 2" premiere when he told us straight-up ... MMA fighters don't stand a chance against boxers in a BOXING MATCH!

Heavyweight boxing champ Anthony Joshua is a freak of an athlete.

6'6", 234 lbs and explosive as all hell.

Yet he sucks at dunking a basketball.

Here's video of the K.O. king getting rocked by the rim at the Under Armour headquarters in Baltimore -- where he's been promoting his upcoming superfight with Wladimir Klitschko.

Don't worry AJ, even superfreak athletes like Dez Bryant get stuffed by the rim every now and then.

Still funny though.

Floyd Mayweather says he's all about giving fans what they want ... and they want him in the ring with Conor McGregor.

Floyd added fuel to the fire Saturday night as he yakked with Showtime's Jim Gray, after Conor said his sights are set on fighting the boxing champ.

Floyd hedges for sure, but keeps coming back to the central point ... he's more than open to the fight.

UFC star Khabib Nurmagomedov says he's the Floyd Mayweather of MMA -- and if the boxer wants a REAL fight ... he'll happily meet him in the street!!!

TMZ Sports spoke with the 28-year-old Russian who says he's ready to BREAK Tony Ferguson when they face off at UFC 209 in March ... and then he'll smash Conor McGregor.

In fact, Khabib warned Conor and Floyd Mayweather that he's a force to be reckoned with ... and if either one gets in his way, he'll destroy them.

He eats sleeps and breathes MMA -- and refuses to even THINK about any other sport.

Here's a 2014 interview with Oscar De La Hoya addressing his alcoholism head-on -- saying the daily battle was a "monster" that he was constantly trying to control.

De La Hoya opened up to Graham Bensinger ... saying he started drinking at 8 years old and things became a problem in his early teens.

At the time, Oscar -- who had been to rehab twice before -- said he had a grip on his drinking but admitted it was a day-to-day struggle.

Oscar relapsed this week and was arrested for DUI in Pasadena.

Oscar De La Hoya was arrested for DUI in Pasadena, CA Tuesday night ... TMZ Sports has learned.

Law enforcement sources tell us the 43-year-old was pulled over for speeding in a Land Rover around 2 AM and during the stop, officers suspected he was drunk.

We're told Oscar bombed a series of field sobriety tests and was arrested for DUI. He was cited and released to his manager.

Earlier in the evening, Oscar was seen at multiple bars in the area, including Barney's Beanery in Old Town Pasadena where he posed for a pic with a fan.

Oscar has struggled with substance abuse for years -- and has been to rehab for alcohol and drug issues in the past.

Story developing ...

Floyd Mayweather's insanely expensive Bugatti didn't sell at auction this weekend ... despite a $1.9 MILLION bid ... because the number was still much lower than Floyd was hoping to get.

As we previously reported, Floyd put his white 2011 Veyron Grand Sport on the auction block at the Barrett-Jackson auto show in Scottsdale, AZ this weekend.

The boxer was expecting to make a profit after reportedly paying $3.5 mil for the whip ... but that's not how things went down.

We're told the reserve on the car (the lowest number he would agree to sell the car for) was $2 million ... and the highest bid was still $100,000 short of that. Aerosmith's Steven Tyler had expressed interest in the car, but clearly, things didn't work out.

Our sources tell us Floyd was visibly upset and left the auction early. Now, Floyd has to look for another high-end car buyer ... which isn't impossible ... it's just very time-consuming.

Meantime, Floyd's pal, Justin Bieber, sold his Ferrari for a whopping $430k ... which is higher than some car experts thought it would get!

Props to our friends at Velocity’s Barrett Jackson LIVE for the video.

New IBF champ Gervonta Davis has something much sexier than boxing super stardom on his mind for the future ... telling TMZ Sports now that he's the man, he wants RIHANNA.

22-year-old Davis absolutely DESTROYED Jose Pedraza to take the junior lightweight crown this past Saturday night ... in what some say was a star-making performance.

We talked to Gervonta ... and while he says he's definitely getting more DM thirst since he won the belt, he told us he plans to use is newfound stardom to lure RiRi, claiming he's just her type.

Careful, Gervonta ... we hear there's a seven footer in Philly who's already claimed dibs.

Ronda Rousey could have a golden opportunity to improve her stand-up fighting game -- because Floyd Mayweather says he's willing to work with her ... if she'll give him a chance.

We got Floyd leaving Pristine Jewelers in NYC (he dropped roughly $200k on gifts for family and friends) -- when he told us he has nothing against Ronda and would love to help her out.

"I'll work with her if she's willing to work with me," Floyd said.

Ronda has blasted Floyd in the past over his domestic violence conviction. Floyd fired back by saying he makes way more money than she does.

But now, Mayweather says it's water under the bridge for him ... and it's her call.

WBA boxing champ Daniel Jacobs says he's sure he's gonna beat GGG in their upcoming fight and all because he's already bested an opponent way tougher than Golovkin ... cancer.

Jacobs was diagnosed with osteosarcoma -- a rare form of bone cancer -- in 2011 and missed nearly 19 months from the sport before resuming his career.

We got Jacobs in L.A. and he told us that fight was the toughest of his life ... and because of that ordeal he has absolutely ZERO fear of GGG, who's knocked out his last 23 opponents.

Dana White could not be clearer ... Floyd Mayweather has stupid written on his forehead for dismissing his $25 million offer to fight Conor McGregor.

Dana thinks Floyd should be grateful to him for offering him enough to pay Uncle Sam and Pristine Jewelers.

What's more ... the UFC honcho thinks its ridiculous that Floyd is under the delusion he's worth more than Conor.

We got Floyd out earlier Friday, and he scoffed at Dana's offer.

Tupac Shakur's ticket stub to the Mike Tyson fight he attended the night he was shot has been in very few hands since then, but now it could be in yours ... if ya got a lot o' cash.

Tupac was at the Tyson-Bruce Seldon fight Sept. 7, 1996 at the MGM Grand in Vegas, and after a first round KO by Iron Mike, he allegedly handed his ticket stub to a man and said ... "Here you go boy, enjoy this."

The ticket stub was later bought by a guy who verified it was indeed the rapper's. Now he's looking to sell one of the last items 'Pac ever touched to the highest bidder. Shortly after Tyson's fight, he and Suge Knight famously brawled with rivals in a lobby, then drove off and got shot.

Goldin Auctions owner Ken Goldin thinks the ticket will fetch at least $25,000.

Undefeated boxing star Gervonta Davis -- Floyd Mayweather's top prospect -- says he's so sure he's gonna win his first world title on Saturday he's already got his victory vacation planned.

Davis has been destroying his competition since he turned pro, but has his first title fight this weekend against IBF super featherweight champion Jose Pedraza.

We got Gervonta out in NYC and asked him how he's preparing for the fight ... and he told us he's preparing for the post-fight turnup with an exotic locale in mind for himself and his crew.

Floyd's teaching the kid well ... watch him work below.

Boxing superstar Gennady Golovkin ain't brushing off the possible Conor McGregor vs. Floyd Mayweather fight ... saying the UFC star has a REAL chance to win.

Golovkin joined the guys on the "TMZ Sports" TV show (airs Friday night on FS1) and warned Mayweather not to underestimate the Irish champ.

Floyd Mayweather is shooting down Dana White's $25 MILLION offer to fight Conor McGregor ... saying simply, "You're a f**king comedian!"

Earlier Friday, White appeared on 'The Herd' on FS1 and made the official offer for the fight -- $25 mil each plus part of the Pay-Per-View profits.

Floyd was clearly INSULTED by the offer and told us to look at his watch ... a limited edition Hublot Laferrari which usually starts around $220k and can run up to around $350k.

The message ... Dana's number is WAYYYY too low.

Back to the drawing board.

Soulja Boy needs to clear the air about boxing Chris Brown -- telling us exactly why he's fighting, how the match will end ... and about his struggle to put down weed beforehand.

Soulja sounded focused and pumped about training when we got him Friday at LAX. He says there will definitely be a knockout ... no matter what Mike Tyson says.

He says last he heard -- from Floyd Mayweather -- the fight's happening in Vegas or L.A. ... but Soulja's just getting back from Hong Kong, and we're guessing he missed the update from Wack 100 that it's moving to Dubai.

Soulja also had one final message for Chris, and it's a little hard to believe.
