Spotted on ESPN, where you can read even more on the story:

Mayweather-Maidana II — dubbed “Mayhem” — will go down Sept. 13 at the MGM Grand Garden Arena and headline a Showtime PPV card, the fourth bout of Mayweather’s six-fight deal with Showtime/CBS.

Although the Barclays Center in Brooklyn, New York, has pressed hard to land a Mayweather fight, he is comfortable fighting in his hometown and will lace ’em up at the MGM Grand for the 10th consecutive time.

Mayweather is hoping to erase any doubt about what happened on May 3 when he faced Maidana for the first time and won a majority decision — 117-111, 116-112 and 114-114 — to unify 147-pound world titles in a very tough fight, one of the most competitive and entertaining of his career.

“Marcos Maidana is a tough customer and he gave me a fight that had me work for the victory,” Mayweather said in a news release. “His style is difficult at best, but with experience comes a way and will to win. I’m not one to give second chances in the ring, but I want to give the fans what they want to see. I will be as prepared as I always am when I step in the ring on Sept. 13. I only see the outcome one way and that’s another successful night for me and my team.”
