According to sources in Zanfer Promotions, former champion Rafael Marquez (41-7, 37KOs) is being positioned to return on July 14th at Dallas Cowboys Stadium in Arlington, Texas. One potential opponent being discussed is former champion Wilfredo Vazquez Jr. (21-2-1, 18KOs) of Puerto Rico. Rafael's older brother, Juan Manuel Marquez, will defend his WBO interim-junior welterweight title in the main event. Juan Manuel will possibly face former lightweight king Brandon Rios.
