It’s no secret that UFC President Dana White has been involved with boxing from an early age. White, who began boxing at an early age, then moved into the business side of the boxing world as a manger, where he frequently encountered Floyd Mayweather Jr.

Mayweather recalled being involved with White early on in his career recently, saying:

“Dana White used to come over my house every day,” Mayweather said. “I’ve been knowing Dana White 21 years. I’m big enough to apologize to Dana White. I’m a real man, that’s what real men do. I’m man enough to apologize. I’ve said some stuff about Dana. I’m only human. He takes shots at me; I take shots back. I’m only human. I’m not upset with Dana White, I’m not upset with anybody.”

With that being said, White stated several years ago that he continues to box frequently despite now being 47 years old; Something Joe Rogan believes could lead to CTE. He recently spoke on the Joe Rogan Experience to explain why he thinks White could very well have CTE:

“Dana White is a notorious gambler but he wins millions of dollars sometimes. I think he said he’s lost as much as $1 million and he’s won as much as $7 million in a night.

“[He does it for] thrills. Also, people who have been hit in the head a lot – Dana’s been hit in the head a lot. Notoriously impulsive, notoriously susceptible to addiction, whether it’s gambling addiction, alcohol addiction, it’s a big part of CTE. Chronic Traumatic Encephalopathy. That’s brain damage, from getting hit in the head. He did a lot of boxing when he was young, had his dome rattled.”

“You’re not supposed to get punched in the head ever,” said Rogan. “You’re definitely not supposed to get punched in the head multiple times a day for years.”
