As a result of Georges St-Pierre suffering a knee injury while training for his UFC 137 title defense against Carlos Condit, the bout between Nick Diaz and BJ Penn has been moved to main event status. The fight, according to UFC President Dana White, will remain be three rounds.
Despite the fact that the fight is less than two weeks away, Diaz’s manager, Cesar Gracie is not happy with the fight only being three rounds. Gracie would very much like to see Penn accept a five round fight with Diaz.
“These guys have to prove they are ready. These guys are fighters. BJ has always said he's a warrior. ... The old school days of MMA back when it was NHB, they fought forever. Don't be scared, homie. Let's make it five rounds."
