North American Boxing Association welterweight champion Samuel Vargas has been on boxing’s biggest stage and he’s determined to prove that he still belongs there. The 28-year-old Vargas (27-3-1, 14 KOs) steps up in one of the most significant fights of his career, August 19, as he defends his NABA title against three-time world title challenger Ali “Rush Hour” Funeka (39-6-3, 31 KOs) in the main event of Lee Baxter Promotions’ (LBP) second event at the Brampton Powerade Centre, “Face Off”, in Brampton, Ontario, Canada.
