A superfight between UFC star Conor McGregor and boxing champion Floyd Mayweather could be one step closer to reality following a revelation from UFC president Dana White Wednesday that McGregor has agreed to terms.

White, appearing on TNT’s postgame coverage following Game 1 of Celtics-Cavaliers playoff series, said “The McGregor side is done. I’m starting to work on the Mayweather side now.”

Both sides have been rattling the sabers for some time on the possibility of a showdown. White said Wednesday the fight would be a boxing match.

“I’m not saying the fight will happen, but I got one side done and now it’s time to work on the other. If we can come to a deal with [promoter Al] Haymon and Mayweather, the fight will happen,” White said.

According to TheMacLife.com, which covers mixed martial arts, McGregor confirmed he has signed a contract for the fight. McGregor also took to Twitter to start promoting the fight, tweeting a photo of a child surrounded by his UFC championship belts and the caption “Let’s go get some boxing ones now son.”

Mayweather retired in 2015, but has said he would take the McGregor fight if the terms were right. White has estimated Mayweather could make $100 million and McGregor $75 million in an clash that figures to be among the highest pay-per-view events ever.
