Floyd Mayweather Looks To Match Rocky Marciano By Beating Andre Berto

In what is expected to be the final fight of his illustrious 19-year career, boxing superstar and pound-for-pound king Floyd "Money" Mayweather (48-0, 26 KOs) will put his undefeated record and WBC and WBA Welterweight World Championships on the line against power-punching, two-time welterweight world champion Andre Berto (30-3, 23 KOs) Saturday, Sept. 12 at the MGM Grand Garden Arena in Las Vegas, live on SHOWTIME PPV (8 p.m. ET/5 p.m. PT).

Coming off of the Mayweather vs. Pacquiao event, in which Mayweather remained undefeated by taking a unanimous decision victory, Mayweather will test himself against a hard-hitting fighter hungry for his chance to score a historic upset. Mayweather could also make history. If triumphant, he would match the record of the late heavyweight champion Rocky Marciano, who retired in April 1956 with a record of 49-0. Equaling Marciano's record, one of the most hallowed in all of sports, would reaffirm Mayweather's legendary status in the sport and buttress Mayweather's claim as "The Best Ever. Two stellar world championship fights will also be included on the pay-per-view telecast.
