"He's in a hospital up in North Dakota somewhere right now," said UFC president Dana 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."

But the bad news is not stopping there, more ailment was discovered!

He has other problems too," continued White, "He is not good. He is very, very sick and he's going to be out for a while. I am worried about it..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.
