Floyd Mayweather officially retired after handing Conor McGregor a very lucrative L during their August 2017 bout, but the captain of the Money Team hasn’t completely ruled out the possibility of re-entering the world professional fighting.

“Retirement has been great,” Mayweather told Showtime’s Jim Gray on Saturday. “But as you know and everybody knows, I go in retirement, I come back. Is it possible I come back? Yes. But if I do come back it has to be in the octagon.”

The topic naturally turned to Mayweather’s last opponent, Conor McGregor.

“I spoke with my team,” Mayweather added. “I spoke with Al Haymon. Al Haymon says no. I spoke with Showtime. I spoke with CBS. If we can get together with Dana White and the UFC to make a mega-fight happen—one fight—it could be against Conor McGregor. We don’t know.”

While the logistics of his MMA weight class and commitments with Showtime and CBS would have to be worked out, Mayweather gave the impression his primary concern was securing a big payday for a potential MMA match.

“Absolutely,” Mayweather said, when asked if he would return to professional fighting. “Only if the money is right."

McGregor may have some legal hurdles to clear to get a shot at Mayweather in an official MMA fight. But the fact that Mayweather has gone on record about possibly coming out of retirement to be an MMA fighter means fans might want to keep an eye on his future moves.
