Just moments after pounding Mauricio Rua and taking his title in the main event of UFC 128, Jon Jones learned who his first challenger would be - training partner, Rashad Evans. Rashad stepped into the cage and the fight was announced, both men were happy to set their friendship aside to move forward with the fight. The crowd instantly turned on Rashad, getting the biggest pop of the night. Classic heel turn? Maybe not exactly, but there's never been a crowd that booed quite that loudly when Rashad stepped into the cage before.
