The pair will once again fight in Las Vegas on 13 September.

In that fight, one judge scored it at 114-114 while the other two made it 116-112 and 117-111 in favour of Mayweather.

"I only see the outcome one way and that's another successful night for me and my team," said Mayweather.

"His style is difficult at best, but with experience comes a way and will to win."
