An exciting night of fights at UFC 105 has quickly been overshadowed by serious concerns over Brock Lesnar’s health.

He was recently diagnosed with glandular fever, but it now appears that something else has been discovered that is a cause for greater concern.

Speaking at the UFC 105 post fight press conference Dana White told the assembled media, “I am worried about it.  I can’t really talk about it right now, but (Lesnar) is in rough shape. He’s in really bad shape.”

White said that Lesnar had collapsed while taking time out in Canada recently and was rushed to hospital where a number of tests were carried out.

“He doesn’t want to talk about it publicly, but he’s in bad shape. He’s not well,” White told reporters. “He’s not going to be getting well anytime soon.”

This latest news will send shockwaves throughout the MMA community and beyond.  Brock Lesnar has quickly become both the heavyweight champion of the UFC and the sports biggest PPV draw.

When asked what would happen with the heavyweight title if Lesnar is out for a considerable period of time, White had no definitive answer.

“If it’s a long wait, we’re gong to have to do something,” he said. “We’re going to have to – the last thing I ever want to do is strip a guy who won a title. That’s the last thing I want to do. I don’t know if we’ll have to do an interim or what we’ll do to fix it.”

With Antonio Rodrigo Nogueira now confirmed out of UFC 108 with a staph infection and Shane Carwin undergoing knee surgery it may be some time before a legitimate interim fight can be established.

For the mean time such matters are inconsequential, Lesnar’s health must be everyone’s first concern.  White confirmed that the UFC will do all they can for the fighter.

“I’ve got to get him to one of these really good hospitals with really good doctors to figure out what’s wrong and how we get him better,” he said.
