Speaking with the media during the post fight press conference at UFC 105, White indicated that Brock Lesnar will be out far longer than just UFC 108.
"He's in a hospital up in North Dakota somewhere right now," said White. "He went to Canada and some bad stuff happened to him, so we've got to figure it out.
"He doesn't want to talk about it publicly, but he's in bad shape. He's not well and he's not going to be getting well anytime soon."
Lesnar pulled out of the UFC 106 main event fight with Shane Carwin near the end of October when he realized the illness he had wasn't going away. The fight was then moved temporarily to UFC 108 and didn't stay there long when it was determined shortly thereafter that Lesnar still hadn't recovered.Now the champ is hospitalized with an undisclosed illness and appears to be out indefinitely.
"I am worried about it," said White of his biggest star's medical situation. "You know, I can't really talk about it right now, but he's in rough shape. He's in really bad shape ... and we're going to have to do some stuff to take care of this guy. He is not well and he's not getting any better.
"We're going to have to send him to the Mayo Clinic or to Scripps, or one of those really good hospitals to figure out what's wrong with this guy."
Update: Brock Lesnar underwent minor intestinal surgery to relieve stress in his large intestine which was caused by a bacterial infection. Doctors told him he "wasn't right for a year" and that his system was working so hard to fight it that he became susceptible to other illnesses like mono. Lesnar will rest and then go to the Mayo Clinic in Minnesota to undergo some more tests. The UFC hopes to get Lesnar back as soon as possible but it's going to take some time for him to recover.
