Floyd Mayweather will retire after fighting Andre Berto

Floyd Mayweather's fight against Andre Berto in Las Vegas on September 12 will be the last of his career, according to Mayweather Promotions CEO Leonard Ellerbe.

The undefeated welterweight will equal heavyweight legend Rocky Marciano's long-standing unbeaten record of 49-0 if he defeats Berto.

Mayweather has the opportunity of further cementing his legacy as one of boxing's all-time greats if he can surpass that record and extend his unbeaten record to 50 fights - but his trusted confidant Ellerbe is adamant this will be the final time the 38-year-old will enter the ring.
"This is Floyd's last fight. I'm not trying to sell it that way."This is going to be his last fight. And the fans get a chance to see Floyd in a very, very exciting fight with a guy that we know is coming to fight." Ellerbe said.

Mayweather has faced a storm of criticism since announcing the unfancied Berto as his next opponent in favour of a perceived tougher challenge such as Britain’s Amir Khan.

Berto, 31, is a former Olympian and welterweight champion, but came up short against two previous opponents Mayweather convincingly defeated in Robert Guerrero and Victor Ortiz.
