The Sergey Kovalev-Vyacheslav Shabranskyy HBO card on Nov. 25 at the Theater at Madison Square Garden in New York is undergoing a makeover. The main event remains but the initial plans for a junior lightweight co-feature between former titlist Orlando Salido and Jonathan Oquendo have been scrapped and the card is being expanded into a tripleheader, multiple sources with knowledge of the plans told ESPN. Light heavyweight contender Sullivan Barrera (20-1, 14 KOs) is ticketed to appear in the co-feature against an opponent to be determined. Also, terms have been agreed to for the opening fight, which would pit former secondary junior lightweight titlist Jason Sosa (20-2-4, 15 KOs) against Robinson Castellanos (24-13, 14 KOs) with the winner in position to challenge titleholder Jezreel Corrales, should he defeat Alberto Machado in the main event of HBO’s Oct. 21 card. Castellanos is aiming for a rematch with Corrales, who edged him by 10th-round technical decision on July 15.
