Marvin Hagler vs. Sugar Ray Leonard, billed as The Super Fight, was contested on April 6, 1987 for the WBC and The Ring middleweight titles. In the late summer of 1986, negotiations began for a proposed super fight between long-reigning undisputed middleweight champion Marvelous Marvin Hagler and former two-weight champion Sugar Ray Leonard. Leonard had fought only once since his first professional retirement in 1982, defeating Kevin Howard in 1984, retiring again immediately following the fight after being dissatisfied with his performance. In March 1986, Hagler defeated John Mugabi via 11th round knockout, though Mugabi proved tough competition. Leonard, who was in attendance, observing what he thought was Hagler in decline, decided that he could beat the bigger man, and in May 1986, announced that he would come out of retirement espressly to fight Hagler. Hagler was initially reluctant to fight Leonard, announcing in July 1986 that a fight with Leonard wouldn't happen as he was "seriously thinking of retirement." By the following month, Hagler had a change of heart and agreed to face Leonard in 1987. Hagler was guaranteed $12 million plus a percentage of the revenue, while Leonard was guaranteed $11 million plus 50 percent of the closed circuit television rights in Maryland and the District of Columbia. Hagler ended up with around $20 million and Leonard with around $12 million. The Leonard camp initially proposed a ten round, non-title fight. Leonard insisted on three conditions for the fight that would be crucial to his strategy; first the ring was to be 22x22 feet instead of a smaller ring; second the gloves were to be 10 ounces rather than 8 ounces; and third the fight was to be over 12 rounds instead of the 15 rounds favoured by Hagler. Mike Trainer, Leonard's lawyer and advisor, stated that it was "12 rounds or no fight." In return for accepting these conditions, Hagler was offered a large share of the purse. Hagler had previously held the middleweight title belts of all three major sanctioning bodies, the WBA, WBC and IBF. While the WBC agreed to sanction the bout against Leonard, the WBA stripped Hagler of their title after he chose to face Leonard instead of their mandatory challenger Herol Graham. The IBF, while keeping Hagler as their champion, refused to sanction the fight against Leonard, and said that the IBF middleweight title would be declared vacant if Hagler lost to Leonard. In a poll of sportswriters before the fight, 46 out of 50 picked Hagler to win. Leonard was expected to struggle because of his long lay-off and having never had a fight at middleweight before. Unbeknownst to Hagler or the media at the time, in preparation for the fight Leonard had secretly engaged in four warm-up bouts in private with "top-20-type opponents, against whom he had gone 4–0 with two KOs".

The first fight between Shane Mosley and Ronald "Winky" Wright was a junior middleweight unification bout for undisputed champion at 154. The winner would claim the World Boxing Council Super Welterweight Championship (1st defense by Mosley), World Boxing Association Super Welterweight Championship (1st defense by Mosley), International Boxing Federation Junior Middleweight Championship (5th defense by Wright) and The Ring Magazine Junior Middleweight Championship (1st defense by Mosley). The fight occurred at the Mandalay Bay Resort & Casino in Las Vegas, Nevada on March 13, 2004.
