Mike Tyson vs. Michael Spinks, billed as Once and For All, was a professional boxing match which took place on June 27, 1988. Both fighters were undefeated and each had a claim to being the legitimate heavyweight champion. At the time, Tyson held the belts of all three of the major sanctioning organizations (WBA, WBC, and IBF) while Spinks was The Ring and Boxing Illustrated magazine champion, regarded as "The People's Champion," and was considered the lineal champion. The fight was held at the Convention Hall, Atlantic City, New Jersey U.S., it was at the time the richest fight in boxing history, grossing some $70 million, of which Tyson earned a record purse of around $22 million and Spinks $13.5 million. Tyson won the fight, knocking out Spinks in 91 seconds.
Background
Tyson had won HBO’s Heavyweight World Series, which saw all three major sanctioning bodies cooperate with HBO and Don King Productions to stage a tournament that would produce an undisputed world heavyweight champion. Over the course of eighteen months, he took the WBC title from Trevor Berbick, the WBA title from James “Bonecrusher” Smith, and the IBF title from Tony Tucker and became the first fighter to be regarded as undisputed champion since Leon Spinks in 1978.
However, while Tyson was the sanctioning bodies’ champion, he had not garnered universal recognition as champion. Spinks had entered the tournament as the IBF champion, a title he had held since defeating Larry Holmes in 1985. He competed in two bouts in the tournament and won them both, a disputed 15-round decision in a rematch with Holmes and a knockout over Steffen Tangstad. This had set up a match between Spinks and Tucker, the IBF’s top contender, but Spinks began negotiating to fight Gerry Cooney instead of Tucker and the IBF responded by stripping Spinks, taking him out of the tournament. Despite this, Spinks was still recognized by The Ring as its world champion and was also still considered to be the lineal champion, honors which he had yet to be defeated for.
History
Michael Spinks became a professional boxer shortly after he won the gold medal at middleweight in the 1976 Summer Olympics. Initially, Spinks was more concerned with assisting his brother Leon's rise to the heavyweight championship, but was later convinced to turn pro himself. In 1981 Spinks fought Eddie Mustafa Muhammad for the WBA light heavyweight championship and defeated him by decision to win his first world title. The next year Spinks won the WBC title from Dwight Braxton in 1983 to become the undisputed champion. In 1984, Spinks added the newly created IBF title. In September 1985, after having defended his titles a combined total of ten times, Spinks moved up to the heavyweight class to challenge reigning IBF, Ring, and lineal champion Larry Holmes, who had been champion since 1978. Spinks defeated Holmes in a fifteen-round decision to become the first reigning light heavyweight champion to win the heavyweight championship. Spinks defeated Holmes again in a rematch and then successfully defended his title against Steffen Tangstad. Instead of defending his IBF title against top contender Tony Tucker, Spinks elected to take a more lucrative fight with former contender Gerry Cooney, who had fought three times in five years, in June 1987. The IBF responded by stripping Spinks of the title, but he was still in possession of the lineal and Ring titles and was considered by many to still be the rightful champion.
