Three of the most exciting lighter weight champions are in action on Friday night at Gymnasio TV Azteca in Mexico City. WBC super-flyweight champion Juan Francisco Estrada (40-3, 27 KOs) defends his title in a rematch with Carlos Cuadras (39-3-1, 27 KOs). Former top pound for pound fighter Chocolatito Gonzalez (49-2, 41 KOs) defends his WBA superflyweight belt against Israel Gonzalez (25-3, 11 KOs). The obvious goal is here to set up an unification rematch between Estrada and Chocolatito. The two previously met in 2012 in a great fight for the WBA light-flyweight title that Chocalito won. The extremely entertaining WBC flyweight champion Julio Cesar Martinez (16-1, 12 KOs) will go up against late replacement Moises Calleros (33-9-1, 17 KOs).
