Floyd Mayweather Jr. said "MMA next" to Conor McGregor during the staredown in their press conference on Monday, the UFC lightweight champion revealed.
He spoke to MMAFighting's Ariel Helwani (warning: contains NSFW language):
McGregor will fight the 49-0 boxing legend in the ring on August 26.
While that fight will be on Money's terms, the American seemed to imply during the press conference that he would be willing to take on McGregor on the Irishman's home turf, per MMAJunkie's Chamatkar Sandhu:
Indeed, per MMAJunkie, Mayweather also said: "I don't give a [expletive] if it's in the ring, I don't give a [expletive] if it's in the Octagon, put me in there, and I'm going to kick [expletive]."
McGregor hit back immediately: "Don't be talking [expletive]. You do give a [expletive] if it's in the Octagon."
The Notorious' coach John Kavanagh welcomed the possibility of the pair clashing in an MMA match:
UFC.com's Matt Parrino has his doubts the 40-year-old would actually be prepared to follow up on his claims:
Indeed, as unlikely as the prospect of McGregor beating the undefeated star in his first professional boxing encounter is, the possibility of Mayweather winning a reverse battle is even more implausible.
MMA's acceptance of kicking and grappling would make it almost completely alien to Mayweather.
The talk will likely turn to the possibility of the pair facing off in the Octagon, assuming McGregor is unable to pull off an upset in the ring.
However, given how great the mismatch will be in that context—even relative to their current matchup—it may not be able to generate much genuine interest, nor is Mayweather likely to be actually prepared to take part.
