Mayweather, in a surprising move, apologized and praised White, the UFC president, during the MayMac World Tour stop Wednesday at Budweiser Stage here. The two have taken shots at each other — some thinly veiled, others not — for years. But White has helped bring Conor McGregorto the table for this gigantic fight and Mayweather knows good business when he sees it.

“Dana, I could never disrespect you,” Mayweather said on stage. “I’ve known you for 21 years. You’ve done a hell of a job with this company. And I want to continue to watch you grow. I want to watch you continue to build the UFC, because it’s all about combat sports. You’ve done a hell of a job. No matter what I’ve said about you in the past, as a man I look in your face and apologize and tell you I’m sorry. But you’ve done a hell of a job with this company.”
