8 Biggest Mysteries Still Surrounding WrestleMania 34

8. Will Samoa Joe Wrestle?

Absent since January, the injured Samoa Joe was reportedly backstage at last night's Raw (as per PW Insider), but WWE opted against including him on the WrestleMania 34 go-home show.

The former NXT Champion has been suffering from a bout of plantar fasciitis. A potentially serious foot condition, it can keep athletes sidelined for months, but while WWE are yet to confirm that Joe has been cleared to return, if he was at Raw, there's a good chance he's on the comeback trail.

This makes WrestleMania a real possibility, with rumours suggesting he'll be added to The Miz, Seth Rollins, and Finn Balor's three-way Intercontinental Title match. This on-the-night addition would make for an exciting moment, and with Joe set to wrestle the trio for the belt at April 27th's Greatest Royal Rumble event, it's easy to connect the dots.

Throwing him in the Andre The Giant Memorial Battle Royal is another option, but unless he was booked to win, this'd be a disappointment. Joe was omitted from 'Mania 33, but has been consistently excellent since arriving on the main roster. He deserves a decent spot, and if he's healthy, joining the IC Title bout would provide that.
