Billed as "The Fight of the Century", this contest between Muhammad Ali and Joe Frazier would be the first time in history that two undefeated fighters faced each other for the heavyweight title.

In 1971, both Ali and Frazier had legitimate claims to the title of World Heavyweight Champion. An undefeated Ali had won the title from Sonny Liston in Miami Beach in 1964, and successfully defended his belt up until he had it stripped by boxing authorities for refusing induction into the armed forces in 1967.

In Ali's absence, the undefeated Frazier garnered two championship belts through knockouts of Buster Mathis and Jimmy Ellis. He was recognized by boxing authorities as the World Champion. Unlike Mathis and Ellis, Frazier was plausibly Ali's superior, which created a tremendous amount of hype and anticipation for a match pitting the two undefeated fighters against one another to decide who was the true heavyweight champ.

The fight itself exceeded even its promotional hype and went the full 15-round championship distance. At the end of round 14 Frazier held a lead on all three scorecards (by scores of 8–6–0, 10–4–0, and 8–6–0). Early in round 15, Frazier landed a left hook that put Ali on his back. Ali, his jaw swollen grotesquely, got up from the blow quickly, and managed to stay on his feet for the rest of the round despite several terrific blows from Frazier. A few minutes later the judges made it official: Frazier had retained the title with a unanimous decision, dealing Ali his first professional loss
