Undefeated welterweight champion Floyd Mayweather is to have a rematch with Argentina's Marcos Maidana.
American Mayweather, 37, will defend his World Boxing Council and World Boxing Association titles against Maidana, whom he beat by a majority decision on 3 May.
The two will again meet in Las Vegas on 13 September.
"I only see the outcome one way and that's another successful night for me and my team," said Mayweather.
"I'm not one to give second chances in the ring, but I want to give the fans what they want to see.

|"Mayweather was pressured all the way by the battling Maidana [in May]."The crowd howled at the end, but many of the punches thrown by Maidana hit Mayweather's arms or shoulders or missed the target altogether."|
"His style is difficult at best, but with experience comes a way and will to win."
In the previous fight in May, one judge scored 114-114 while the other two made it 116-112 and 117-111 to Mayweather.
