If I remember correctly he had a portion of his colon or intestine removed. Thats a very serious complication of serious gastrointestinal issues. I've had colitis for about 20 years and haven't had to have that done, thank goodness.
I meant no disrespect, Lesnar's a god damn icon for the sport and by far one of the most incredible specimens I know of in any sport, even outside of the UFC. I just thought I heard he broke an ankle or tore an ACL or some shit after he coached the Ultimate Fighter guys with Junior Dos Santos. I was mistaken, give me a break!
I mean, that scene that season where his diverticulitis was acting up and Dana was so accommodating and telling him what a value he was to the league should tell you everything you need to know about the guy's work ethic. We all know Dana can be a dick to promote the UFC, but when Lesnar called him to apologize all he would say was how much he needs to take all the time he needs and not worry about the consequences. It was honestly kind of refreshing to see in a professional sport.
Honestly the guy could have a great career selling work--out equipment on TV. It's disappointing that he didn't reign at least as long as Tim Silvia, though... I fucking hate Tim Silvia and Lesner is so much more of a great example of a heavy-weight champ.
