As previously reported, Dave Meltzer mentioned in the latest installment of The Wrestling Observer Newsletter that AJ Styles probably won’t be facing John Cena at next year’s WrestleMania but instead The Undertaker was one of the names rumored as an opponent for Cena on the card.
It’s worth noting that the @WrestleVotes Twitter account, the same account that broke the story about Neville walking out on WWE, mentioned that Undertaker vs. Cena is not definite but it’s certainly “on the table” as a match being discussed for next year’s show.
Hearing Taker vs Cena is not definite but certainly "on the table". Many in WWE are still convinced Taker is done, hip surgery or not. Could be a result of his direct relationship with Vince. He only needs to tell him, & no one else. And Vince keeps everything w/ Taker hush.

Speaking of Undertaker vs. Cena, there is a poster floating around on the internet for the match. That poster is a fake and was made by a fan several months back.
