BBC Sport - Floyd Mayweather: Andre Berto 'tough' opponent for final fight
Mayweather relishing last ever fight
- From the section Boxing
Floyd Mayweather says he chose Andre Berto as his opponent for his final fight because he is a "rough and tough" competitor.
Mayweather is unbeaten in 48 professional bouts and victory over fellow American Berto - who has won 30 of his 33 professional fights - in Las Vegas on Saturday would see him equal Rocky Marciano's career record of 49-0.
Many believe he will not be able to resist attempting to break Marciano's mark, but the 38-year-old says his health is more important.
