As of right now, no one is really sure if The Undertaker will be making an appearance at WrestleMania.
With just a couple of weeks left until the Showcase of the Immortals, it's pretty obvious that booking him for a match is highly unlikely and it does seem as if he's been distancing himself from WWE in recent months by taking on bookings for various convention appearances and interviews.
However, it's now been revealed that The Undertaker is being advertised on the side of a WrestleMania production truck alongside Seth Rollins, Ronda Rousey, Samoa Joe, and Big E.
This points to WWE once considering using the Deadman on the Grandest Stage of Them All but plans clearly changed and his future with WWE remains as unclear as John Cena (who also isn't booked for a match as things stand). Stay tunes for updates.
