UFC welterweight champion Georges St-Pierre was battling the effects of a fever, according to his trainer Firas Zahabi. GSP defeated Nick Diaz via decision over the weekend at UFC 158: St-Pierre Vs. Diaz.
Zahabi, during a recent appearance on The MMA Hour, disclosed that St-Pierre was "a bit warm," but the thought to pull out of the fight was never mentioned.

"Everybody is a little injured, everybody is a bit busted up," Zahabi said. "He wasn't sick enough to pull the plug on the fight, but he did have the start of the fever. He was warm and he was feeling a little uneasy. He was feeling a little sick."

GSP mentioned taking some extra time off following the victory, saying he has been going full-force since knee surgery. Johny Hendricks is expected to be his next foe whenever he returns to action.
