During Monday night's episode of RAW, Triple H accepted the Match of the Year Award for his WrestleMania 28 match with The Undertaker. He then in his speech noted, "You've not seen the last of the Undertaker," after which JBL quickly mentioned the Streak.
This was likely a tease for the Dead Man's return to work a match at WrestleMania, much like has been done with Shawn Michaels a couple of years ago.
We reported the following on December 6th, 2012:
We can confirm that The Undertaker reached out to WWE during the past week or so and has told the company that he wants to work the WrestleMania 29 pay-per-view. He is currently training for a return and pitched a potential opponent for the event. At this time, it is known that the possible opponent will NOT be Triple H or Ryback. Of course, plans can change.
For those unaware, 'Taker has a gym and full-sized wrestling ring at his home he shares with his wife Michelle McCool.
