Floyd Mayweather has announced that he will square off against former-welterweight champion Andre Berto on 12 September in his attempt to equal Rocky Marciano's 49-fight undefeated streak.
The unbeaten American boxer said that he always bring his A-game and insisted that the fight against Berto would be no exception, the BBC reported.
Mayweather, who defeated Manny Pacquiao on points in their lucrative meeting in May, insisted that he is going to make it 49.
Earlier, Mayweather had claimed that his 49th fight in September would be the last when his current six-fight deal with American broadcaster Showtime expires.
