Mayweather vs Berto September 12th!

Ding ding!  It's on!  Floyd Mayweather Jr.’s attempt to match late heavyweight champion Rocky Marciano's 49-0 record at retirement will come against former welterweight world champion Andre Berto Sept. 12 at MGM Grand in Las Vegas.

Mayweather told the Los Angeles Times, "’I'm ready to get back in the ring on September 12 and prove again to the whole world why I’m ‘The Best Ever,’" said Mayweather.

"I always bring my A-game and this fight against Andre Berto is no exception. He’s a young, strong fighter who is hungry to take down the best. Forty-eight have tried before and on September 12, I’m going to make it 49."
