LAS VEGAS (SEPT 23) Last night at the Mandalay Bay Events Center, in front of a crowd of 4,708 boxing fans, Fernando "Vicious" Vargas, 153 1/2,  (22-1 (20KO)  became the International Boxing Association and World Boxing Association 154-pound titles when he stopped southpaw Jose "Shibata" Flores, 153 1/2,  in the seventh round.  The event was filled with emotion as just prior to the Vargas/Flores fight, there was a tribute to those who lost their lives in the September 11 New York terrorist attack.  Both Vargas and Flores came into the ring for the tribute instead of having the traditional entrance that boxers usually go through.
