Oh, and according to The Wrestling Observer, the Undertaker is currently scheduled to take on John Cena at WrestleMania 33 in a match that was originally supposed to happen last year, but was cancelled due to an injury to Cena.
WWE officials are concerned that an Undertaker-Cena match doesn't build for the future, and so there's still consideration being given to a match pitting The Undertaker against Roman Reigns. Being as how both Cena and Reigns are getting world title shots at the Royal Rumble, 'Taker could end up as a WrestleMania challenger.
Three bouts for the show are currently set in stone - The Big Show versus Shaquille O'Neal, Goldberg versus Brock Lesnar, and Seth Rollins versus Triple H. Also tentatively planned for the show are a multiple-woman match for the Raw Women's Championship, Kevin Owens versus Chris Jericho, and - if Reigns doesn't fight Undertaker - Roman Reigns versus Braun Strowman.
