Boxer Floyd Mayweather Jr. says he has one last fight in him. He plans to cap off his 19-year undefeated career as well as put his WBC and WBA welterweight world championships on the line against two-time welterweight world champion Andre Berto on Sept. 12 at the MGM Grand Garden Arena. Ticket information is still up in the air but may be available later this week.
Mayweather's last fight in May against Manny Pacquiao resulted in a lackluster unanimous decision victory in a clash dubbed the "Fight of the Century." If he wins this final fight in September, his record will match the late heavyweight champion Rocky Marciano, who retired in April 1956 with a record of 49-0.
The card includes a bout for the super-middleweight title between champion Badou Jack and challenger George Graves, and the WBO super-featherweight title goes up for grabs when champion Roman Martinez faces Orlando Salido, a rematch of a bout Martinez won by unanimous decision in April.
