the other participants in the Final Four match (the other was Vader, who had no further involvement in the ongoing storyline). Due to being the runner-up to the title at Final Four, Undertaker was made the number one contender and was booked to challenge Sycho Sid for the title at WrestleMania. However, on the March 17 edition of Raw Is War, Sid defended the title against Hart in a steel cage match, with the winner defending his title at WrestleMania. During the match, both Undertaker and Austin interfered. Undertaker came out to help Sid because he wanted to wrestle Sid for the title while Austin helped Hart because he wanted to make his scheduled submission match with Hart a title match. Sid won the match and retained his title and as a result, Sid vs. Undertaker remained the main event of WrestleMania. The second main match on the card was Bret Hart versus Stone Cold Steve Austin in a Submission match. Hart and Austin's rivalry began after Austin won the 1996 King of the Ring tournament and began taunting Hart, who was inactive at the time. Austin insulted Hart in his speeches so Hart would accept his challenge to a match. Hart returned in October and accepted Austin's challenge, with the two facing each other at Survivor Series 1996 where Hart defeated Austin. Their rivalry continued as Hart and Austin were the final two participants in the 1997 Royal Rumble match. Hart had originally eliminated Austin from the match but Austin's elimination was considered unofficial because the officials did not see it as they were busy attending to a brawl between eliminated wrestlers Mankind and Terry Funk. They were participants in a Four Corners Elimination match for the vacant WWF Championship at Final Four, which Hart won. The next night on Monday Night Raw, Austin cost Hart the WWF Championship against Sycho Sid when Hart had applied the Sharpshooter on Sid, Austin nailed Hart with a steel chair followed by Sid powerbombing Hart for the win. Hart and Austin were booked to wrestle in a submission match at WrestleMania, but Hart got a shot at the WWF Championship in a steel cage match on the March 17 edition of Raw Is War, with the winner defending the title against The Undertaker at WrestleMania 13. Hart almost had the match won, until Undertaker interfered and helped Sid in getting the victory.
