SONORA, MEXICO — Hernan “Tyson” Marquez (32-2, 25 KOs) closed the book on his budding Luis Concepcion (23-3, 18 KOs) rivalry with three emphatic knockdowns in route to a shocking first round TKO.
Concepcion started aggressively with left jabs. Marquez responded by timing the punch with cuffing right hooks that knocked Concepcion off-balance. Undeterred, Concepcion continued jabbing forward and firing right crosses and uppercuts. Marquez countered with another right hook which badly stunned Concepcion before several more hooks deposited him on the canvas.
Concepcion got up quickly and was immediately assaulted with more power shots. Marquez bullied Concepcion to the ropes and scored a second knockdown, again off a short right hook. Concepcion unwisely tried to stand his ground, throwing a haymaker right which Marquez promptly countered with a left cross for the third knockdown and referee stoppage.
The rematch victory is Marquez’s second WBA flyweight title defense since winning the belt from Concepcion in April.
