Floyd Mayweather's apparent plans to enter the world of Mixed Martial Arts would result in a legacy tarnished, according to a former UFC champion.
The record-breaking undefeated boxer, who retired late year after a stoppage win over Conor McGregor, hinted at a return to combat sports on social media this week, but inside the Octagon.
The 40-year-old mocked McGregor with a caption reading: "Come on King, you better not miss."
Former UFC middleweight champion Michael Bisping has warned the boxer known as 'Money' that his legacy is at risk, if he is seriously contemplating a switch to MMA to rematch the Irishman.
Bisping stated on his podcast, Believe You Me, that McGregor would "destroy" Mayweather in a cage.
"If he does fight in the UFC, it's going to be against Conor McGregor ... Conor McGregor in an MMA fight will f****** destroy Floyd Mayweather like he's never seen," Bisping said.
"I think he's probably trolling people.
"I don't know what he's doing, he's maybe trying to stay relevant, maybe he's trying to hype his next boxing match, maybe he's trying to get a rematch with Conor McGregor in the boxing world. I don't know what he's doing."
UFC president Dana White recently confirmed a brief discussion with Mayweather about a potential billion-dollar multi-fight deal with the MMA leader.
Bisping said, with money like that involved, anything is possible and he would watch, regardless of the perceived mismatch.
"Who wouldn't watch if? I'd watch it... of course I would.
"It would certainly be a record-breaking pay-per-view. I don't know if it'll be more than McGregor vs Mayweather in a boxing ring, but it certainly has the potential."
