Not everyone thought Khabib Nurmagomedov was being serious when he called Floyd Mayweather out to a boxing fight after beating Conor McGregor at UFC 229.

“Hey let’s go Floyd, we have to fight now,” Nurmagomedov said in a video that surfaced a week after the Russian’s win over McGregor.

Khabib is seen smiling in the footage, hence why many people thought he was having a laugh.

But the rumours have only spiralled since, with Mayweather himself fuelling the discussion.

"We fighting," the American told TMZ. "I'm my own boss, so I can't say what's going on at Khabib's end, but at my end we can make it happen.

"I'm Floyd Mayweather. I'm the A-side, you call me out you come into my world.”

There would no doubt be an enormous amount of interest in the fight, particularly after Nurmagomedov’s victory over McGregor.

White reacts to the rumours

But according to UFC president Dana White, we shouldn’t get our hopes up.

White has quashed rumours of a fight, insisting that he hasn’t been contacted by anyone associated with Mayweather’s team regarding a boxing match against the UFC lightweight champion.

"Don't pay attention to it," White told ESPN.

"First of all, the Mayweather team has not approached us at all.

“Khabib is under contract with the UFC. Floyd is very good about getting his name out there when he wants to."

White seems assured of himself.

But remember, the thought of Mayweather fighting McGregor seemed ludicrous when it was first touted, and the pair ended up meeting in Las Vegas in a fight that gripped the world.

Nurmagomedov, currently under suspension by the Nevada State Athletic Commission, would entertain the idea of a fight against the 50-0 star.

That’s according to his manager Ali Abdelaziz.

“We're open, if Floyd wants to box Khabib,” Abdelaziz told ESPN.

White says not to pay attention to all the talk, but it’s hard to ignore it.
