Late blows hit Floyd Mayweather camp ahead of fight

Welcome to fight day. Wagging tongues will be replaced by flying fists when UFC star Conor McGregor and boxing legend Floyd Mayweather fight for bragging rights in Las Vegas today.

The megafight the world's been waiting for is bigger than anything we've ever seen in combat sports. The last time there was this much hype surrounding a match-up was for Mayweather's bout against Manny Pacquiao in 2015, but today's boxing match will overshadow that in every aspect.

The American is as good as it gets with the gloves on, coming out of retirement to put his 49-0 professional record on the line. But McGregor is a winner. He's shown in his career if he wants something, he'll go and grab it. It's why he made history by becoming the first fighter to hold simultaneous titles in two weight divisions in the UFC.

"The Notorious" has never boxed professionally before, so the smart money's on Mayweather. He's paying $3.75 on Sportsbet.com.au to win by decision while McGregor's paying $4.35 to knock the American out. Everyone that's seen just how damaging McGregor's left hand can be is aware he only needs one punch to win the fight and shock the world.

Late blows hit Team Mayweather

Team Mayweather was forced to make a late adjustment on fight day after a daring disruption by Conor McGregor's fans.

The Irish have taken over Las Vegas ahead of today's megafight and they were up to mischief last night.

A TMT "The Money Team" billboard positioned on one of the major roads here was hilariously defaced.

The artists wrote 49-1 in large white numbers to reveal their prediction of what Mayweather's record - currently 49-0 - will be after today's fight. And finished the job by painting an Irish flag.

Workmen were forced to remove the flag and cover the writing early this morning.

McGregor's countrymen dominated the crowd at yesterday's weigh-in and were singing in the streets well into the night.

"There's a saying, you'll never beat the Irish," McGregor said. "You can't beat us. We roll in and take over wherever we want. Las Vegas is Ireland now."

The slight comes after Team Mayweather was dealt a crushing blow at yesterday's weigh-in when the American's protege - IBF super featherweight champion Gervonta Davis - was stripped of his title for failing to make weight ahead of his fight against Francisco Fonseca on Sunday's undercard.

Davis missed the 130-pound (60kg) limit by two pounds, ending any hopes he had of defending his belt. The fight will still go ahead but if Davis wins, his strap will remain unclaimed.

Mayweather Promotions represents the 22-year-old, who boasts an 18-0 record with 17 knockouts.

"There are a lot of fighters who are world champions who are not as big as Gervonta is," Mayweather once said about him. "He's connected to me but also he can fight. I would say this: Gervonta is not just the youngest world champion, he's one of the most exciting fighters in boxing."

This isn't the first time Davis has had weight troubles, needing three attempts to make weight when he first defended his title against Liam Walsh in May. Mayweather was ringside on that occasion, barking instructions at the youngster as he destroyed Walsh inside three rounds.

"Tank (Davis) is the future of boxing. He's me from a few years ago - same burning ambition," Mayweather said after that bout.

The undercard had already suffered a blow when former IBF welterweight champion Shawn Porter pulled out of his fight against Thomas Dulorme because of personal reasons including a death in the family. He has been replaced by 2008 Olympic Bronze medallist Yordenis Ugas.
