After Lopez beats Vasquez he attacks Vazquez’s trainer.
Lopez stops Vazquez in the 11th round at the Roberto Clemente Coliseum in San Juan, Puerto Rico. Vasquez suffered an eye injury that caused him problems in the 11th. The southpaw Lopez then hit with a blizzard of punches to put him down on the canvas. The referee stops the fight immediately, at 2:29 of the round, rather than letting Vasquez attempt to get up from the knockdown.
