UFC President Dana White responded to these rumors by saying that they're possible and that the talks between the two sides are serious.
McGregor (21-3 MMA, 9-1 UFC), the No. 1 ranked fighter in the USA TODAY Sports/MMAjunkie MMA lightweight rankings and No. 3 pound-for-pound fighter, has yet to defend the lightweight title he won in November 2016. "I don't see that being a problem", White said.
While Mayweather has never competed in an MMA fight, one thing he has done is defeat UFC Lightweight Champion Conor McGregor in a boxing match this past August.
As UFC continues to sit and wait, hopeful that its biggest star Conor McGregor will make a summer return in 2018, there remains an uncomfortable stat that's repeatedly floated around concerning the lightweight champion.More news: Russia Accuses The US Of Supporting ISIS - Again
"For people to suggest that, you're just a Conor hater", White told ESPN. It is Conor's fault he did Mayweather, but we made a decision to do the Mayweather fight and everybody gave a f--. "He fought everybody on his way up 145 pounds". McGregor and Diaz ultimately fought twice, after Diaz won the first contest.
During the build-up to the Mayweather vs. McGregor fight Mayweather teased several times that he'd fight in the UFC next, and the Irishman welcomed that opportunity with open arms. "And after the fight, every fighter in the UFC gave him props for representing the sport". Waiting in the wings is interim champion Tony Ferguson. It looks like if Conor McGregor doesn't come back promptly to fight Tony Ferguson, he will not be stripped. But shortly after winning, GSP vacated the title and cited health reasons. If Conor McGregor doesn't fight, the UFC will go on.
Despite the situation, the UFC executive said his recent conversations with McGregor haven't been about fighting. "If he wants to come back, [UFC welterweight champion] Tyron Woodley or [middleweight champion] Robert Whittaker is waiting for him".
