The fight is set to take place later this year in Las Vegas with each fighter set to earn up to $100 million.

White said the deal was all but done. 

“The McGregor side is done, I’m starting to work on the Mayweather side now,” White revealed when speaking to TNT.

“I’m not saying the fight will happen, but I got one side done, now it’s time to work on the other.

“If we can come to a deal with [Al] Haymon and [Floyd] Mayweather, the fight’s going to happen.”

McGregor said he was ecstatic to have his part of the deal done.

“It is an honour 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.”
