If you saw Raw last night, you witnessed John Cena in rare form. He recapped his loss at the Elimination Chamber, and he said that for a split second he thought his dreams of being at WrestleMania were through.
Then he got the WWE Universe's hopes up by issuing a challenge to The Undertaker. A second later, he said that a match between himself and The Undertaker would not be possible. He said that he will be appearing on Smackdown Live on Tuesday to find another route to WrestleMania.
The Undertaker has not wrestled since last year's epic WrestleMania match between himself and Roman Reigns. When he lost the match, we watched Taker bid farewell to the squared circle. Recently, the WWE Universe started buzzing about the possibility of The Undertaker having another go at wrestling. He had been seen at many events, and he made an appearance at the 25th anniversary of WWE Raw. During that appearance, he made a rather puzzling speech, making people wonder if there is a possibility of him coming back.
According to his Wikipedia profile, he is "no longer retired." Could The Undertaker be planning a return? We don't know. All I know is that I'd love to see the Deadman walk again.
As for John Cena, I honestly don't see him getting a match via the Smackdown route. The only wrestlers on Smackdown that could be potential opponents are Baron Corbin, Randy Orton, and Jinder Mahal.
