10 things that could happen if Undertaker and Shawn Michaels meet in the ring.

#9. This will probably be Shawn's last match ever.

Shawn Michaels was 'retired' by the Undertaker years ago, and there's no doubt that his full time wrestling schedule is done for good. However, he feels that he has at least one more great performance left in his body--and this will likely be that final great performance.

With his unmatched legacy--Triple crown champion, household name, Playgirl model--Michaels could just let things lie, but if he comes back for this match it will likely be his swan song.
