WWE WrestleMania 35: 10 Last-Minute Rumours You Need To Know

6. John Cena's Unannounced Comeback?

Rumour: After wrapping up filming on his latest movie (Playing With Fire is due for release next year and is currently in post-production), John Cena has a gap in his schedule. Everyone and their gran guesses that this means 'Big Match John' will waltz back into the WWE sphere for a few weeks and work a match at WrestleMania.

Likelihood: It's possible provided WWE have something cool for him to do. Is there a demand for a rematch with The Undertaker, for example? Further, just how much excitement would there be if Cena's trademark theme hit and he cut a promo before working a squash match win like The Rock did at 'Mania 32 over Erick Rowan?

There are rumours suggesting Cena will replace Baron Corbin as Kurt Angle's farewell opponent. That'd make the most sense, because both men have history; Angle was Cena's first televised rival in WWE back in 2002, and this would be neat closure on that chapter of their lives.
