Dana White and Conor McGregor have come to terms for one side of the Mayweather vs. McGregor boxing match.

White announced that tonight on TNT after the Cleveland Cavaliers vs. Boston Celtics basketball game.

“McGregor’s side is done,” said White, when being interviewed by Shaquille O’Neal, a longtime UFC fan who at one point asked if he could fight in the organization. “I’m starting to work on the Mayweather side now. I got one side done, now it’s time to work on the other. If we can come to a deal with Haymon and Mayweather, the fight’s going to happen.

McGregor, on his own website TheMacLife.com, confirmed that he has signed for the fight.

“It is an honor to sign this record breaking deal alongside my partners Zuffa, LLC, the Ultimate Fighting Championship and Paradigm Sports Management,” McGregor said. “The first, and most important part of this historic contract has now officially been signed off on. Congratulations to all parties involved. We now await Al Haymon and his boxer’s signature in the coming days.”
