Conor McGregor has been acting a fool during the promotional tour that he’s currently on with Floyd Mayweather to hype up their upcoming fight. From making racist remarks to taking shots at 50 Cent, the guy has gotten pretty out of control thus far—and Mayweather and McGregor still have one stop left on their promo tour in London on Friday.

But despite his erratic behavior during the tour, UFC president Dana White expects McGregor to be on his best behavior on Aug. 26 when the fight goes down. We’re sure McGregor will still put on a show before—and potentially after—the fight. But once the fight starts, White doesn’t expect McGregor to go crazy in the ring and brutally attack Mayweather with a bunch of MMA moves or anything. That’s because, according to White, there’s a clause in McGregor’s contract that could cause him to lose a lot of money if he decides to use a single MMA tactic on Mayweather.

"He would get sued beyond belief if he does anything but hit Floyd Mayweather with his hands to the head and body," White said on Thursday, according to USA Today Sports. "It would be very bad. That can’t happen. That can’t happen. There’s actually language in the contract that that can’t happen."

As it stands, White is predicting McGregor could make in the high eight figures for the fight. But he said McGregor would "100 percent" put his purse in jeopardy if he were to resort to his MMA ways with Mayweather.

"Forget about the contract," White said. "[Mayweather] would just sue [McGregor]. And it would destroy Conor’s life because Mayweather would win…Conor is a bit of a wild man. But he likes money as much as Floyd does. If he wants Floyd to have all his money, that’s the way to do it."

Given all the animosity and tension that will be present when Mayweather and McGregor fight, it wouldn’t be too surprising to see McGregor get overly emotional. But after hearing what White had to say about the ramifications of him flipping out, we wouldn’t expect to see him lose his mind and attack Mayweather at any point.
