5 reasons why Vince McMahon won't allow The Undertaker to perform at WrestleMania 35

#4 He got the John Cena match

Around 2015-16, there were rumours about John Cena and The Undertaker finally having a dream clash at WrestleMania 32. It's still believed that this was the originally planned match, but Cena's ill-timed injury prevented him from wrestling at WrestleMania 32.

Instead, The Undertaker faced Shane McMahon. The following year, they could have faced each other, but they didn't because WWE felt it was time for Roman Reigns to be the one to retire The Undertaker.

The feeling the prior year was that the Cena-'Taker match at WrestleMania was all that was really left for The Deadman in his career. He would end up finally getting the dream match a year later, but it wasn't how people expected it to go down. The "feud" was just John Cena desperately calling The Undertaker out, and when he finally did get the match, it lasted all but 165 seconds.

With that match out of the way, there might be a feeling that there isn't anything left for The Undertaker.
