American boxer Floyd Mayweather has revealed that he will be retiring in September.

Ahead of his much anticipated May 2 with Manny Pacquiao, the American meet the media on Tuesday, April 14 in Las Vegas.

When asked about how long he will remain in the sports, Mayweather said there will be just one fight after his mega-bout with Manny Pacquiao.

"I'm pretty much done with all this," Mayweather said. 

"It's not fun like it was back then, it's business now. I don't really enjoy it any longer."

Mayweather wants to fulfil the sixth and last fight of his mega-millions Showtime pay-per-view contract before finally bowing out.
