A Chávez–Haugen super lightweight title fight was originally announced in October 1992 to take place on December 5 that same year at Caesars Palace in the Las Vegas Valley. Organized by promoter Don King, the Showtime pay-per-view event was also set to include a WBC super welterweight title fight between Terry Norris and Simon Brown and a WBA super middleweight title rematch between Michael Nunn and Víctor Córdoba.[2] However, only two weeks later, the entire card was cancelled due to rival network HBO airing an episode of HBO World Championship Boxing featuring James Toney and Iran Barkley on the same day. On December 1, 1992, King announced a new event billed as The Grand Slam of Boxing scheduled to take place on February 20, 1993, in Estadio Azteca in Chávez's native Mexico. Headlined by Chávez and Haugen, the card was originally announced to once again include the Norris–Brown super welterweight title bout, as well as Julian Jackson defending his WBC middleweight title against Gerald McClellan and a WBC super featherweight title bout between Azumah Nelson and Gabriel Ruelas. However, Jackson was forced to pull out of his fight with McClellan due to an injury to his right hand and that fight was replaced with a WBA super middleweight fight between Nunn and Danny Morgan, while Brown required surgery for a detached retina and was replaced by Maurice Blocker.
