WBC/WBO/WBA welterweight champion Floyd Mayweather Jr. (48-0, 26KOs) is still maintaining that his upcoming fight, on September 12th at the MGM Grand in Las Vegas, will be his final ring appearance.

"I'm almost at the big 4-0, I'm getting close [to 40-years-old]. I don't need 50, I'm okay with 49," Mayweather said.

And most don't believe Mayweather will call it a career in September. If he does fight again, fight number 50 would be the expected end-game to his career - in May of 2016.

Mayweather was back in action last month, winning a twelve round unanimous decision over Manny Pacquiao in a fight that broke every possible financial record in boxing.
