GSP vs. Hughes III - UFC 79: Nemesis

Yep, it's officially on since Matt Serra declared that he was injured and could not fight at UFC 79 against Matt Hughes and there is an interim Welterweight title at stake too according to UFC.com

Dana White: “Obviously, the loss of Matt Serra was brutal, but the great thing about the UFC is that we can put together great fights like Hughes-St-Pierre at a moment’s notice and bounce right back,” said UFC President Dana White. “I have the utmost respect for both Hughes and St-Pierre for stepping up for this fight, and not only are the fans going to see two of the greatest welterweights of all-time settle their score in a rubber match, but they're going to do it in a five round interim title fight, and the winner is going to face off next year against Matt Serra for the undisputed title.”

GSP: “I’m so excited to get this fight,” said St-Pierre. “I’m fighting Matt Hughes for the interim title right now, and then after that I’m going to go after Serra. I’ve wanted that rematch against Serra, and this is the best scenario that can happen.”

Matt Serra: “I can’t believe the position this puts me in,”.“I’m actually rooting for Matt Hughes so I can beat his ass.”
