Showtime Sports will offer a live stream of the Floyd Mayweather vs. Andre Berto undercard final press conference ahead of the pay-per-view card which takes place on Saturday, September 12, 2015 live on Showtime pay-per-view from MGM Grand in Las Vegas.
In what is expected to be the final fight of his hall of fame career, Mayweather (48-0, 26 KOs) will put his undefeated record on the line against the all-action Berto (30-3, 23 KOs), a veteran of eight world title fights who has long been considered a potential opponent for Mayweather.
If triumphant, Mayweather would match the record of the late heavyweight champion Rocky Marciano, who retired in April 1956 with a record of 49-0.
