'Jaded' Mayweather says Pacquiao bout will be second-last fight of his boxing career

Unbeaten US boxing champion Floyd Mayweather has revealed that his highly anticipated bout with Filipino boxer and politician Manny Pacquiao would be followed by just one more fight because he no longer enjoys the sport.

Mayweather's May 2 bout with Pacquiao, which is being touted as the fight of the century, is the fifth of a six-fight contract with broadcaster Showtime. And the American boxer says that the fun has gone out of boxing, which he now regards as a job.

Mayweather claimed that he doesn't enjoy boxing like he once did, adding that his last fight will be in September, the BBC reported.

Mayweather took part in an open training session before revealing that the Pacquiao bout at the MGM Hotel in Las Vegas would see two fighters meeting at the pinnacle of our careers. He added that Pacquiao is a future hall-of-famer, and he himself is a future hall-of-famer.

WBA and WBC champion Mayweather is unbeaten in 47 professional fights, while his opponent has lost five and drawn two of his 57 fights.

After Mayweather defeated Oscar De La Hoya in May 2007, he relinquished his WBC light-middleweight title, only to come out of his brief retirement in July to announce his fight with Britain's Ricky Hatton. He also retired in 2008 but returned 21 months later in May 2009 to fight Juan Manuel Marquez, the report added.
