At a January 24, 1974, rematch at New York City’s Madison Square Garden, Ali defeated Frazier by decision in 12 rounds. On October 30 of that same year, an underdog Ali bested George Forman and reclaimed his heavyweight champion belt at the hugely hyped “Rumble in the Jungle” in Kinshasa, Zaire, with a knockout in the eighth round. On October 1, 1975, Ali met Joe Frazier for a third time at the “Thrilla in Manila” in the Philippines and defeated him in 14 rounds. On February 15, 1978, Ali lost the title to Leon Spinks in a 15-round split decision. However, seven months later, on September 15, Ali won it back. In June 1979, Ali announced he was retiring from boxing. He returned to the ring on October 2, 1980, and fought heavyweight champ Larry Holmes, who knocked him out in the 11th round. After losing to Trevor Berbick on December 11, 1981, Ali left the ring for the final time, with a 56-5 record. He is the only fighter to be heavyweight champion three times. In 1984, it was revealed Ali had Parkinson’s disease.
