Floyd Mayweather wouldn't last a minute in the Octagon with Conor McGregor, according to UFC announcer Bruce Buffer.

The pair met in a Las Vegas boxing ring in 2017 when Mayweather used all of his experience to outclass and eventually stop McGregor in the tenth round.

It extended Mayweather's record to 50-0 and since then the American recently took his show to Japan where he beat Japanese kickboxer Tenshin Nasukawa in an exhibition boxing match, while McGregor returned to the UFC only to suffer a submission loss to the undefeated Khabib Nurmagomedov last October.

There have been persistent rumours that Mayweather and McGregor could have a rematch - this time under mixed martial arts rules.

However, UFC man Buffer, half brother of boxing announcer Michael Buffer, thinks it would be no contest.

"Mayweather would probably get beat within a minute," Buffer told Express Sport.

"He has never suffered leg kicks and getting taken down like that.

"He would have to train for at least six months or 12 months.

"If he could learn how to sprawl when somebody tries to take him down. If he could learn how to get out of submissions.

"But this is not something you learn within a week."

He added: "McGregor is a Mixed Martial Artist.

"A guy like Mayweather, he has trained all of his life, he is a fantastic athlete, but he has never been kicked in the leg.

"If you have never been kicked in the leg, trust me, it is going to hurt."
