Johannesburg - Floyd Mayweather jnr says he'll fight for the last time in September next year.
Mayweather told guests at a gala dinner in South Africa on Friday that he remembers his first fight when he was a kid in 1987, and that "September 2015 will be my last."
The unbeaten five-division world champion, considered by many the best boxer of his era, said after beating Canelo Alvarez in a dominating display last September that he had four fights and two years left in his career.
Mayweather's next bout will be in May against an undecided opponent, having said this week that British fighter Amir Khan and Argentine Marcos Maidana are the leading contenders.
Mayweather has a 45-0 record with 26 knockouts and made his pro debut in 1996.
