How can you watch it? We have everything you need to know right here. The pay-per-view event kicks off at 6 p.
We wouldn't hold our breath waiting for the boxing great to make the switch to the Octagon but, apparently, the world's preeminent MMA organisation wanted to see Mayweather come out of retirement for some five-minute rounds under their banner.
Mayweather hung up his gloves for good in August after making a return to the ring for a special, one-off fight with UFC lightweight champion Conor McGregor under boxing rules. The meeting of combat sports' two biggest pay-per-view draws was pretty one-sided when it eventually went down in the T-Mobile Arena but it would definitely be a different story if takedowns, submissions, kicks, elbows and knees were permitted.
And Mayweather has revealed in a recent rant on Instagram that he'd been contacted about a potential rematch with 'The Notorious' with 4oz. I can come right back to the UFC.
If I want, I can go. The year-old clearly saw McGregor as an easy payday but we don't reckon the earning potential of a UFC fight would be enough to tempt him to sign on the dotted line.
And you already know I went from the streets to the executive suites.
