Light heavyweight contender Sullivan Barrera now has an opponent for his bout on HBO on Nov. 25 at the Theater at Madison Square Garden in New York. Barrera (20-1, 14 KOs), 35, a Cuban defector fighting out of Miami, will face former interim world titleholder Felix Valera (15-1, 13 KOs), 29, of the Dominican Republic, in a scheduled 10-round fight on the undercard of the show headlined by former unified light heavyweight titleholder Sergey Kovalev facing Vyacheslav Sharbranskyy. Barrera-Valera has been "signed, sealed and delivered,” a source with knowledge of the deal told ESPN on Thursday but who was not authorized to talk about it until the fight is formally announced.
