Due to the controversy of the UFC 104 decision, a rematch was immediately announced and took place at "UFC 113" on 8 May 2010 in Montreal. Rua won via knockout at 3:35 of round 1, after dropping Machida with a right and following up with punches on the ground. He was awarded the UFC Light heavyweight Championship, becoming just the second fighter to have won PRIDE and UFC titles. Following the victory, Rua underwent surgery in June to repair a knee injured during the bout against Machida.
