Floyd Mayweather has confirmed a rematch with Marcos Maidana will take place in Las Vegas on September 13.
Mayweather maintained his unbeaten record - and added the WBA welterweight title to his WBC belt - with a points victory over Maidana in May.
But one judge scored it an even contest, and Mayweather said in the immediate aftermath of victory he was prepared to give the Argentine a rematch.
Now the American has proved as good as his word, tweeting: #Mayhem Mayweather vs. Maidana 2 September 13, 2014 MGM Grand in Las Vegas Live on Showtime PPV.
Confirmation of the fight ends any chance Amir Khan might have had of facing Mayweather next.
Khan was an impressive winner over Luis Collazo on the undercard of Mayweather-Maidana I and has long sought a fight with boxing's biggest name.
