Frazier beat Ali on points in the so-called 'Fight of the Century' in 1971, but lost in two further meetings including the epic 'Thrilla in Manila' in 1975.

Ali said: "The world has lost a great champion. I will always remember Joe with respect and admiration. My sympathy goes out to his family and loved ones." The pair had an at-times fraught relationship, dating back to taunts Ali directed at his rival in the build-up to their famous trilogy of fights. But they were reported to have been on better terms in recent years.
