26 July 1971 v Jimmy Ellis: TKO-12
Against his some-time sparring partner Ellis – they had grown up together in Louisville – Ali proved stronger and faster but dragged the match out to the 12th round when he called for the match to be ended, so his friend would not be hurt any more.

20 February 1976 v Jean Pierre Coopman: KO-5

30 April 1976 v Jimmy Young: W-15
By now Ali had become slow and tired, whereas Young displayed pace and stamina to go the whole 15 rounds. But Young also ducked out of the ropes several times to avoid his opponent and at one point the referee called a knock down and started the count. But Ali had too much skill and retained the title on a unanimous decision.
24 May 1976 v Richard Dunn: TKO-5

Evangelista, a Uruguayan-Spanish boxer, challenged Ali for his title but lost by unanimous decision in the 15th.
29 September 1977 v Earnie Shavers: W-15

15 February 1978 v Leon Spinks: L-15
Ali had expected an easy fight against Spinks but was surprisingly outmanoeuvred by his opponent who won on points. It was only Spinks's eighth professional fight, and it was the fastest rise of a boxer to become world heavyweight champion in the sport's history.
15 September 1978 Leon Spinks: W-15
Ali exacted swift revenge on Spinks to regain the title. Ali was always in control at the Superdome in New Orleans, where the 63,350 was the largest indoor attendance for a boxing match, and won a unanimous decision to become the first boxer to win the world title three times.
2 October 1980 v Larry Holmes: L - TKO - 10
After a short-lived retirement Ali found himself back in the ring against the new world champion. It was a heartbreaking encounter. Holmes battered the 38-year-old Ali and he lost the match by knock out in the 11th round.
11 December 1981 v Trevor Berbick: L-10
The career that began with such a thrilling bang ended in anticlimax against Berbick. After seven quite even rounds, Berbick dominated the last three and ran out the winner on a unanimous verdict.
