Ali lost his title in February 1978 to 1976 Olympic champion Leon Spinks. In losing to the novice Spinks, Ali became the first heavyweight champion in the entire history of boxing to lose his title to a novice who had only seven professional fights. In the September rematch in New Orleans at the Superdome, Ali was given a 15-round decision over the disoriented Spinks. Then on June 27, 1979, he announced his retirement and vacated the title.
