Michael John Nunn (born April 14, 1963) is an American former professional boxer who competed from 1984 to 2002. He is a two-weight world champion, having held the IBFmiddleweight title from 1988 to 1991, and the WBAsuper middleweight title from 1992 to 1994. During both those reigns, he also held the lineal championship. In 2004, Nunn was sentenced to 24 years in prison for drug trafficking; he was released in February 2019.
Nunn won three Iowa Golden Gloves titles and posted an amateur record of 168-8. At the 1984 Olympic trials, U.S. boxing officials asked Nunn, who was boxing as a 156-pounder, to move up to the 165-pound division. They wanted to clear the way for Frank Tate, the eventual Olympic gold medalist, who was being heralded as America’s next great middleweight. Tate’s last loss was to Nunn.
After agreeing to move up in weight, Nunn boxed Virgil Hill at the Olympic trials in Fort Worth, Texas. Hill defeated Nunn by a 4-1 decision. Nunn and Hill boxed again at the Olympic box-offs in Las Vegas, Nevada. Nunn won the first box-off by a 5-0 decision. In the second box-off, Hill dropped Nunn and won by a 5-0 decision to make the Olympic team as the U.S. representative in the 165-pound division.
Nunn turned professional in 1984. After winning his first thirty fights, he fought IBF middleweight title-holder Frank Tate, who was 23-0. The fight took place on July 28, 1988 at Caesar’s Palace in Las Vegas. Nunn won the title by a ninth-round knockout.
In his first title defense, he knocked out Juan Roldan in the eighth round. His second defense was a stunning first-round knockout of Sumbu Kalambay to capture the vacant lineal middleweight championship. Nunn’s next two title defenses were twelve-round majority decision wins over Iran Barkley and Marlon Starling. For his fifth defense, Nunn went to France and knocked out Donald Curry in ten rounds. On May 10, 1991, in his hometown of Davenport, Iowa, Nunn lost his title in a big upset to James Toney. Nunn, well ahead on points after ten rounds, was knocked out after being dropped by a left hook in the eleventh round.
After the loss, Nunn moved up a weight division to super middleweight and won the NABF title with a tenth-round stoppage against Randall Yonker. On September 12, 1992, Nunn won the WBA and lineal super middleweight titles with a controversial twelve-round split decision over Victor Cordoba. The WBA ordered a rematch, which took place on January 30, 1993. Nunn fought much better in the rematch, winning by a one-sided twelve-round unanimous decision.
In his fifth title defense, Nunn lost the title to Steve Little by a twelve-round split decision on February 26, 1994, in another huge upset. On December 17, 1994, Nunn traveled to Ecuador to fight Frankie Liles in an attempt to regain the lineal and WBA super middleweight titles. In a very close fight, Liles, who had defeated Little in his previous fight to win the title, defeated Nunn by a twelve-round unanimous decision.
After nine consecutive wins, Nunn got another title shot. On March 21, 1998, he fought Graciano Rocchigiani for the vacant WBC light heavyweight title in Germany. Nunn lost by a twelve-round split decision, with the judges favouring Rocchigiani’s fewer, more solid punches over Nunn’s much higher volume of lighter shots.
On January 23, 2002, Nunn defeated Vinson Durhan by a ten-round unanimous decision at Caesars Indiana in Bridgeport, Indiana. It would be his last fight. He finished with a record of 58-4 with 37 knockouts.
