Michael Spinks (born July 13, 1956 in St. Louis, Missouri) is a retired American boxer who was a world champion in the light-heavyweight and heavyweight divisions. Nicknamed Jinx, which spawned the nickname of his right hand: The Spinks Jinx, he is the brother of former heavyweight champion Leon Spinks, and uncle of Cory Spinks, a former welterweight and light middleweight champion.

Spinks won the 1974 156-pound Golden Gloves Light Middleweight Championship by defeating Wilber Cameron in Denver, Colorado and then took the Silver Medal in the National AAU 165-pound Championship Competition in 1975, losing in three rounds to Tom Sullivan in Shreveport, Louisiana. He rebounded to take the 1976 National Golden Gloves Middleweight championship with a three-round victory over Lamont Kirkland in Miami, Florida, and that same year captured the United States Olympic Trials Middleweight Championship by defeating Keith Broom in Cincinnati, Ohio. He went on to defeat the Soviet Union’s Rufat Riskiev to win the Gold Medal at the 1976 Summer Olympics in Montreal. Spinks finished with a 93-7 amateur record with 35 knockouts.

Larry Holmes (born November 3, 1949) is a former professional boxer. He grew up in Easton, Pennsylvania, which gave birth to his boxing nickname, The Easton Assassin.

Holmes, whose left jab is considered one of the greatest weapons in the history of sports, was the WBC Heavyweight Champion from 1978 to 1983, The Ring Heavyweight Champion from 1980 to 1985, and the IBF Heavyweight Champion from 1983 to 1985. He made twenty successful title defenses, second only to Joe Louis' twenty-five.

Holmes won his first forty-eight professional bouts, almost matching Rocky Marciano's streak of 49 straight wins, including victories over Ken Norton, Muhammad Ali, Gerry Cooney, and Marvis Frazier. He is frequently ranked by many boxing experts as one of the greatest heavyweight fighters of all time.

Holmes was the fourth of twelve children born to John and Flossie Holmes. When the family moved to Easton in 1954, Holmes' father went to Connecticut, where he worked as a gardener until his death in 1970. He visited his family every three weeks. "He didn't forsake us," said Flossie Holmes. "He just didn't have anything to give." The family survived on welfare.

Michael Gerard "Mike" Tyson (born June 30, 1966) is a retired American professional boxer. Tyson is a former undisputed heavyweight champion of the world and holds the record as the youngest boxer to win the WBC, WBA and IBF heavyweight titles at 20 years, 4 months and 22 days old. Tyson won his first 19 professional bouts by knockout, with 12 of them occurring in the first round. He won the WBC title in 1986 after defeating Trevor Berbick by a TKO in the second round. In 1987, Tyson added the WBA and IBF titles after defeating James Smith and Tony Tucker. He was the first heavyweight boxer to simultaneously hold the WBA, WBC and IBF titles, and the only heavyweight to individually unify them.

In 1988, Tyson became the lineal champion when he knocked out Michael Spinks in the first 91 seconds of the fight. Tyson successfully defended the world heavyweight championship nine times, including victories over Larry Holmes and Frank Bruno. Tyson lost his titles to 42-to-1 underdog James "Buster" Douglas on February 11, 1990, in Tokyo, Japan, by a knockout in round 10. Tyson continued in his quest to regain the titles, defeating Donovan Ruddock twice in 1991. Tyson was then scheduled to take on the undisputed heavyweight champion Evander Holyfield but pulled out due to injury.
