Conor McGregor isn't the only fight star stealing headlines this weekend.
Floyd Mayweather, the undefeated boxer who retired after taking his record to a 50-0 by defeating McGregor last year, has gone out of his way to revive discussion of his potential entry to the UFC.
Interviewed during a Showtime boxing broadcast that's he's promoting in Las Vegas today, Mayweather was asked if he was truly retired.
"Retirement has been great," he told Jim Gray. "But as you know, and everybody know, I go in retirement, I come back. 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.
"I spoke with my team. I spoke with (advisor) Al Haymon. Al Haymon says no. But I spoke to Showtime, I spoke to CBS. If we can get together with Dana White and the UFC to make a megafight happen. It could be against Conor McGregor, we don't know. But Showtime and CBS have to be involved if we do a multi-fight MMA deal."
