Triple G don't scare Daniel Jacobs ... the guy he's fighting tonight ... 'cause his opponent says he fears NO MAN after already conquering cancer.

DJ and Gennady Golovkin are squaring off at Madison Square Garden ... where GGG will attempt to make Jacobs his 24th straight knockout victim.

Pierce Brosnan is ALL ABOUT the Fighting Irish on St. Paddy's Day ... telling TMZ Sports his fellow countryman, Conor McGregor, will DESTROY Floyd Mayweather if they actually square up.

There's a BIG difference between a "business fight" and a "true fight" ... so says Gennady Golvkin who tells TMZ Sports the Conor vs. Floyd situation is more entertainment than sport.

Gennady is gearing up for his big showdown with Daniel Jacobs at Madison Square Garden on Saturday night ... a match GGG says is a "true fight."

By the way, Triple G has been calling Mayweather out for years ... and says he KNOWS he would knock him out.

Floyd Mayweather had made it loud and clear -- he's willing to step out of retirement to fight Conor McGregor ... if they can just hammer out a deal.

Floyd made the official announcement Saturday, saying "for Conor McGregor, I'm coming out of retirement ... just to fight Conor McGregor."

He added ... "I don't want to hear no more excuses about the money, about the UFC. Sign the paper with the UFC so you can fight me in June. Simple and plain. Let's fight in June. You're the B side, I'm the A side."

Here's the problem ... Dana White has already said the fight isn't likely to happen because negotiations are falling apart. They seem to be worlds apart on money ... and there's simply no deal as of February.

Floyd's been back and forth about being willing to fight Conor, but seems to be taking a firm position now ... he's willing if a deal can be struck.

Your move, Dana.

Muhammad Ali's son was stopped and questioned again at another airport ... and his lawyer says the TSA is lying by trying to minimize the incident.

Muhammad Ali, Jr. was at Reagan National Airport Friday when he tried checking in for a flight at an airline counter. Ali's lawyer says a computer check flagged Ali and someone who needed to ante up more info about him. The lawyer says the agent wouldn't accept Ali's Illinois ID, and then put the boxer's son on the phone with Homeland Security.

The lawyer says the call lasted 20 minutes. Once Ali handed over his passport to confirm his identity, the lawyer says Homeland security cleared him.

TSA says the delay was not 20 minutes -- only 11, adding Ali was never "detained."

Oscar De La Hoya has been hit with 2 misdemeanor DUI charges stemming from his January arrest in Pasadena ... TMZ Sports has learned.

Boxing champ Terence Crawford found himself playing the role of referee during a violent girl-on-girl street fight in Omaha ... and one of the combatants was his own sister.

Here's the deal ... a woman named Mystery Wakefield says she was working at the Citi Trends clothing shop in Omaha when she was approached by Terence's sister who wanted to fight.

Mystery says she clocked out of her job (don't wanna fight on company time) and met Iesha Crawford outside ... where they proceeded to throw down.

Terence -- who was recently released from jail -- can be seen trying to break up the fight.

The boxer eventually left the scene, but cops tracked down his car and pulled him over. A gun was found inside the vehicle and he was taken to a nearby station for questioning. He was later released with no charges.

As for why the women were fighting and why Terence was there ... we're still looking into it.

Even Conor McGregor IMPERSONATORS got balls -- including the one who got right up in Floyd Mayweather's face and challenged him to a fight in England.

It all went down during a Q&A event in Birmingham over the weekend -- when Irish impressionist Al Foran grabbed the mic and started talking authentic McGregorian trash right to the champ.

At one point, he even took a seat next to Floyd on the stage and continued the smacktalk.

Meanwhile, the REAL Conor was close by in Ireland this weekend celebrating his mom's birthday ... not too far for a surprise confrontation??

2:19 PM PT -- A rep for the Ladywood Fire Station -- which responded to the fire -- tells TMZ that 2 individuals chucked a Molotov cocktail inside after breaking a window with a brick. We're told the van was connected to Floyd's entourage and the team handling his promotions while he's in the UK. Sources close to Floyd tell us the van was not actually owned by him. The case has been passed off to cops.

Floyd Mayweather had one of his entourage's vans burnt to a crisp in what appears to be an arson attack this weekend in the UK.

Floyd was speaking at an event inside the International Convention Centre in Birmingham Saturday night when 1 of his custom TMT vans was torched outside and left smoldering.

The boxer is currently on his "Undefeated" tour, where he's speaking in front of audiences and doing meet-and-greets with fans.

We've reached out to local authorities ... so far, no word back.

There's a silver lining for Floyd here -- he lost just 1 van ... as opposed to 4 expensive cars like the last time this happened.

Story developing ...

Here's boxer David Allen using some genital intimidation tactics at a weigh-in for his fight in London ... and it's working.

Allen (10-2-1) is fighting David Howe at the O2 Arena this weekend ... and hopes to prove he's the total package.

Forget Conor McGregor ... Floyd Mayweather could have a superfight with a BOXER -- because undefeated champ Danny Garcia says he wants a piece of Money May after he beats Keith Thurman this weekend.

Garcia -- the reigning WBC welterweight champion -- is 33-0 and says beating the also undefeated Thurman on Saturday night would help him get to the next level of big money fights.

He joined the guys on the "TMZ Sports" TV show (airs Thursday on FS1) and explained why he wants either Floyd or Manny Pacquiao next ... and says he's 100% confident he can beat 'em BOTH.

What really happened to Ivan Drago after that crushing (yet satisfying) loss to Rocky Balboa???

Dolph Lundgren has a few ideas ... and they involve brutal Russian punishment and a job with the Putin administration.

Dolph appeared on the Hallmark Channel's "Home & Family" (airs Thursday morning) where he was asked to pick up Drago's life story from where it left off in 1985 after Rocky beat that ass in Moscow.

Long story short ... dude had it rough. But screw him -- he killed Apollo.

It's not even close ... if Conor McGregor fights Floyd Mayweather, Muhammad Ali would've rooted for the IRISHMAN ... so says the champ's ex-wife.

Floyd Mayweather's Vegas home was broken into this weekend while the boxer was in L.A. celebrating his 40th birthday ... and we're told thieves got away with $150k worth of stuff.

TMZ Sports has learned ... Mayweather is listed as the victim in a burglary report for a home he owns in a gated community next to a golf course.

Law enforcement sources tell us it appears someone forced a door open into the home office in the back of the house and stole several purses.

Other sources connected to the investigation tell us there is also at least 1 expensive watch unaccounted for ... and possibly other items missing.

Our law enforcement sources say cops have been in contact with Floyd's camp and the boxer has been instructed to take an inventory of his valuables.

Conor McGregor has been hitting the boxing gym with an Irish boxing sensation -- who tells TMZ Sports the UFC star is 100% confident the fight with Floyd Mayweather will actually take place.

We spoke with 25-year-old Michael Conlan -- who won an Olympic bronze medal for Ireland in 2012. Conlan says he became friends with McGregor a while back and the two have been tight ever since.

In fact, Conlan says McGregor has agreed to carry the Irish flag when Conlan walks to the ring during his upcoming pro fighting debut on St. Patrick's Day at Madison Square Garden.

In the meantime, both Conlan and Conor have been training together at an L.A. boxing gym -- as recently captured by TheMacLife.com.

We asked Conlan how McGregor's boxing training is going -- one thing's clear ... he's definitely impressed.

Deontay Wilder was still ready to swing hours after defending his belt -- getting in the middle of a hotel brawl involving heavyweight contender Dominic Breazeale ... and TMZ Sports got video of the melee.

The chaos erupted in the lobby of the Westin in Birmingham, Alabama ... just across the street from the arena, where hours earlier Wilder scored a 5th round KO of Gerald Washington. In the video, you can see Wilder give someone a huge shove. Breazeale doesn't appear to be the one who received the blow.

The champ mentioned in a post-fight news conference he had beef with Breazeale -- who had fought on the undercard -- and it appears it all came to a head when their entourages met in the lobby.

Cops reportedly broke up the fight after it spilled into the hotel parking lot. Neither Wilder or Breazeale was arrested, but Dominic made it clear on social media ... this feud is just getting started.
