The Undertaker won't be seen on TV until Wrestlemania
WWE’s current plan is to keep The Undertaker off TV until his WrestleMania match against Bray Wyatt itself. This is so they can build anticipation for his physical appearance as many fans are wondering whether he’s truly recovered from last year.
It’s likely that Wyatt will continue to talk down to him in promos, building all the way to Undertaker’s WrestleMania entrance where he immediately reveals himself to be fighting fit. It’s also likely that there will be some kind of interaction, be it cryptic videos and the lights going out etc, but there are no plans for the man himself to appear live on Raw or taped on SmackDown.
Despite wanting to keep things a surprise a photo has already emerged showing Undertaker in the gym.
