Numbers have yet to be confirmed, but Mayweather has previously stated he would take no less than $100 million guaranteed, and offered $15 million to McGregor. The iconic 1997 Evander Holyfield vs. Mike Tyson match pulled in a total of $100.2 million dollars, and the 2007 Oscar De La Hoya vs. Mayweather match netted $136 million dollars.

"All these UFC guys, they are very tough, tough guys. He doesn't have to watch for takedowns.' But to understand your way around the ring, to know when it's time to punch, to not punch, when to dictate pace or back off, those are things that you'd need years in boxing to really understand", he said. "But as far as strictly adhering to boxing rules?"
One point that is getting little attention so far is that Mayweather is coming out of retirement at risk to his undefeated 49-0 record, an unblemished mark which now ties former heavyweight champion Rocky Marciano.
A win for Mayweather would move him ahead of former heavyweight great Rocky Marciano, who also retired with a ideal 49-0 career record.
