Former WBA interim flyweight champion Luis “Nica” Concepcion (29-3, 21 KOs) scored a one-sided twelve round unanimous decision over Nestor Narvaez (19-2-2, 9 KOs) on Saturday night in a bout for the WBC silver flyweight belt at the Roberto Duran Arena in Panama City. “Nica” mostly punished Narvaez, brother of WBO super flyweight champion Omar Narvaez, dropping him in round five with a barrage of punches. Concepcion was deducted a point in round eight for a borderline low blow. The action subsided significantly over the last half of the fight. Scores were 118-108, 118-108, 118-109.
