Former unified bantamweight champ Nonito Donaire (27-1, 18 KOs) is moving up in weight in search of another world title, when he takes on Wilfredo Vazquez Jr. (21-1-1, 18 KOs) for the vacant WBO junior featherweight title on Feb. 4. Donaire's meeting with Vazquez will serve as the co-featured bout to Julio Cesar Chavez Jr.'s title defense against Marco Antonio Rubio.
Already having held titles at flyweight and bantamweight, Donaire looks to become a triple-crown winner, after Jorge Arce, the man who gave Vazquez Jr. his first pro loss last year, vacated that very same title.
