5 biggest mysteries heading into WrestleMania 34

#4 The John Cena-Undertaker situation

Will the Deadman even have a match at 'Mania?

Most fans, including myself, were almost sure that The Undertaker would appear on the final Raw before WrestleMania and accept Cena's challenge, thus making their match official at WrestleMania. But fans were left baffled as the Deadman no-showed yet again.

While this seemed like a questionable decision by WWE at first, on second thought, this decision has just made the Show of Shows more exciting than ever. It is almost a given that The Phenom will make an appearance at the PPV and till he appears, the fans will wait with bated breath for the gong to strike. A genius move by the WWE.
