From what i've read Shawn Michaels was supposed to drop the title to Austin at Wrestlemania 14 in 98. Shawn's back was gone and he was on his way out anyways. A day before the event, Shawn was bitching saying he didn't want to job to Austin and so on. Undertaker basicallly said that if he didn't do the job, he'd have to deal with him. As Michaels was getting ready for the match, Taker was taping his fists in front of Shawn warning him to finish it as planned.
