Brock Lesnar’s trainer Greg Nelson recently gave Yahoo! Sports an update on Lesnar’s illness.

Nelson said:

“I’m not sure exactly what it is he has, mono or whatever, but I know that he was sick and couldn’t get a good, hard workout in. There’s a big difference between making an appearance and smiling and waving at a football game and going out and doing what he has to do in his training.”

The fight between Brock Lesnar and Shane Carwin is currently scheduled to take place at UFC 108 in January. However, it is possible that the bout may be pushed back to February if Lesnar doesn’t recover from the illness soon.
