WBA heavyweight title eliminator matches

By 1966, Ellis was fighting as a heavyweight. When Ali was stripped of the world title for refusing to enter the military, the World Boxing Association staged an eight-man tournament that featured most of the top heavyweight contenders. Ellis, who was ranked eighth in the world after eight consecutive wins, was invited to be in the tournament. Joe Frazier, ranked second by the WBA, chose not to participate in the tournament. Instead, Frazier fought for the vacant New York State Athletic Commission World Heavyweight Championship, which he won with an eleventh-round knockout of Buster Mathis.

In the opening round of the tournament, Ellis fought Leotis Martin on August 5, 1967, in Houston, Texas. Ellis, the betting underdog, battered Martin's face into a bloody mask, and the referee stopped the fight in the ninth round.

Ellis met Oscar Bonavena in the second round of the tournament. The fight took place on December 2, 1967, in Louisville, Kentucky. Ellis, once again the underdog, dropped Bonavena with a right once in the third round and once in the tenth. After twelve rounds, Ellis was awarded a unanimous decision. This fight was regarded as one of the best of his career. He seemed to be in control for most of the fight apart from the ninth round. Ellis advanced to the tournament final.^[9]

WBA heavyweight champion

In the tournament final, Ellis faced Jerry Quarry, a slight betting favorite, on April 27, 1968, in Oakland, California.^[10] In a dull fight, Ellis fought what Sports Illustrated called "a tactical masterpiece". A cautious Ellis won a 15-round split decision^[11] to capture the vacant WBA Heavyweight Championship. Quarry said, "If they'd given me the decision, I'd have given it back. I didn't deserve it."^[12][13]

Title reign

In his only successful title defense, Ellis defeated Floyd Patterson by a controversial 15-round decision on September 14, 1968, in Stockholm, Sweden. Ellis, who suffered a broken nose in the second round, was awarded the decision by the referee, the sole judge. Many in the crowd of 30,000 disagreed with the decision and started chanting, "Floyd champ!" The New York Times scored the fight seven rounds to six for Ellis, with two even.^[14]

Following the defeat of Patterson, Ellis was out of the ring for seventeen months. He was going to fight Henry Cooper in the United Kingdom, even though the British Boxing Board of Control refused to recognize the fight as a world title bout: the BBBofC was affiliated with the World Boxing Council, who stated that they would only recognize a fight between Joe Frazier and a suitable contender as being for the world title. The fight was postponed a couple of times and eventually cancelled because Cooper injured his knee.^[15] Ellis then planned to fight Bob Cleroux in Montreal, but Cleroux lost what was supposed to be a tune-up fight against the lightly regarded Billy Joiner. Finally, Ellis was going to fight Gregorio Peralta in Argentina, but promoters canceled the fight 24 hours before it was to take place because of poor ticket sales.^[16][17]

On February 16, 1970, Ellis fought Joe Frazier to unify the World Heavyweight Championship at Madison Square Garden in New York City. The undefeated Frazier, a heavy betting favorite, proved to be too strong and powerful. Ellis, who had never been floored as a heavyweight, was knocked down twice in the fourth round by a relentless Frazier. At the request of Ellis': trainer Angelo Dundee, the referee stopped the fight before the start of the fifth round.^[18] It was the first knockout loss for Ellis.

Ellis vs. Ali

After winning his next three fights, Ellis fought Muhammad Ali in the Houston Astrodome on July 26, 1971. Angelo Dundee chose to work with Ellis for the fight. He was Ali's trainer, but he was both manager and trainer for Ellis. Working with Ellis meant that he would get a bigger share of the purse. Ali accepted the arrangement and got Harry Wiley, who had worked with Henry Armstrong and Sugar Ray Robinson, to be his trainer for the Ellis fight.^[19]

Ellis fought well over the first three rounds, but the fight turned after Ellis was hurt by a right hand in the fourth round. The right hand "hurt me so bad I couldn't really fight my best after that," Ellis said. "It ruined me." The referee stopped the fight in the twelfth round as Ali pummelled Ellis.^[20]

After the loss to Ali, Ellis won his next eight fights by knockout. But on June 18, 1973, he fought Earnie Shavers, who was 44–2 (43 KOs), at Madison Square Garden. Ellis, ranked fourth by the WBA, stunned Shavers in the first round with a chopping right to the jaw and backed him into a corner. Shavers took numerous shots in the corner before clinching. After the referee separated the fighters, Shavers put Ellis down for the count with a powerful single right uppercut to the chin. The time was 2:39.^[21]

Ellis came back with a knockout win against club fighter Memphis Al Jones, but with his skills in decline, he went winless in his next five fights. He lost a split decision to Boone Kirkman, fought a draw with Larry Middleton, dropped decisions to Ron Lyle and Joe Bugner, and was stopped in nine rounds in a rematch with Joe Frazier.

The rematch with Frazier took place in Melbourne, Australia, on March 2, 1975. Ellis trained at the Golden Bowl Gym in Camberwell, Melbourne with martial arts 4th Dan Gerry Scaife. Ellis won the first three rounds, but Frazier then picked up the intensity and took control. With Ellis bloody and battered, Angelo Dundee signaled for referee Bob Foster to stop the fight in the ninth round.

Retirement

On May 6, 1975, in what would be his last fight, Ellis knocked out club fighter Carl Baker in the first round. He retired aged 35 after a training injury left him partially blind in his left eye. Ellis finished with a record of 40–12–1 (24 KOs).
