The greatest boxer of the modern age will bring the curtain down on his remarkable career when he fights Andre Berto in Las Vegas. Mayweather’s dynasty is already well-set, but he will seek to emboss it when he attempts victory number 49, tying him with former heavyweight champion Rocky Marciano, who retired undefeated after 49 fights.
Mayweather’s last outing, the Fight of the Century against Manny Pacquiao in May, broke viewing records for boxing on the World of Champions.
