Muhammad Ali

Boxing, United States. Ali and Joe Frazier fought three times. Frazier won the first, the "Fight of the Century" in 1971, handing Ali his first professional defeat; Ali won the rematch in 1974 and the "Thrilla in Manila" in 1975, which ended when Frazier's corner stopped the fight before the 15th round. Ali's insults before their fights were real and hurt Frazier, and Ali later said he regretted them.
