There’s been much speculation as to whether or not The Undertaker will appear at WrestleMania 35 this year. He is believed to be taking more bookings outside of WWE over the next year and will also be much more selective in his booking. 

WWE hasn't really featured The Deadman in any WrestleMania advertising and there has been no reference to his return on television, some sources are even suggesting he will not be appearing at the event, although that seems very unlikely given his importance to the company. 

Today on Twitter, insider @WrestleVotes noted that The Undertaker will be making an appearance at WrestleMania, but it is unknown if he will have a match, although talks are "ongoing".

Getting a ton of Undertaker / WrestleMania questions. Here’s what I’ll say: it would shock me 100% if he didn’t appear on the show. He’ll be there.

TBD as to whether he’s in an actual match or not. Discussions were ongoing this week. Taker news is always tight lipped backstage.
