January 29 – Timothy Bradley defeats Devon Alexander by a tenth round technical decision. The fight was stopped due to a cut Alexander had received from an accidental headbutt in the third round, which was made worse by two more headbutts in the eighth round and an final fourth headbutt in the tenth round. Both fighters came in with undefeated records and the fight was initially praised as one of the few good match-ups between two top ranked Americans in recent years. With the win, Bradley unified the light welterweight titles by defending his WBO title and winning Alexander's WBC title.
