"Rowdy" Roddy Piper replaced Bret "The Hitman" Hitman Hart in the WWF Intercontinental Championship against The Mountie. In kayfabe, Bret's temperature was 102 degrees and was too sick to wrestle on the day of the event. In reality, according to the Wrestling Observer Newsletter, Bret believed his WWF contract was up, and was talking a guaranteed contract with WCW. The plan was to have Bret debut at Clash of the Champions XVIII (1992) two days after the Rumble, possibly with the IC Title (as retaliation for Ric Flair bringing the NWA/WCW World Championship onto WWF programming). Bret's contract, however, had rolled over and he was unable to give notice. His 2007 autobiography "Hitman: My Real Life in the Cartoon World of Wrestling" confirmed the Observer's notes about the plan to lose the belt to Mountie, only for him to regain it from Piper at WrestleMania VIII (1992), but made no mention of agreeing to a WCW deal at that point in time.
