In the weeks after defeating AJ Styles in the Boneyard match at WrestleMania 36, Undertaker was subject of a WWE Network documentary entitled "The Last Ride". At the conclusion of the documentary, the 55-year-old iterated that he had no desire to return to the ring. Both he and WWE confirmed that The Undertaker was now retired.
Speaking on My Mom's Basement podcast, Undertaker said that he verbalized that feeling for the documentary, as a way of putting his foot down, to nullify any temptation on he or the company's part to explore a return to the ring.
However, his boss wasn't too thrilled with that statement.
"I have a whole group of people who are like, 'You can go out and do this, people will go crazy.' On the inside, I'm thinking, 'I don't move the way I used to move, it's a watered down version,'" Undertaker said. "I also love this business so much and love performing. It's almost like I needed somebody to put the bullet in there and stop. Once we started rolling with this, it was in the back of my mind, 'I can get to a point where this will solidify it and I won't have a choice.'
"Originally, that's where I was at until I had to send the last 15 minutes to the Chairman [Vince McMahon]. He didn't like the ending at all. That's where we put the line back in there, 'never say never.' I'm coming to grips with it. Obviously, as we get close to [WrestleMania], I'll have that internal feeling like I should be getting ready for something."
