In a major change of plans WWE is now going ahead with Braun Strowman to face The Undertaker at this year's Wrestlemania. Vince McMahon did push for Brock Lesnar vs Strowman, but was reportedly talked out of it. Instead the leader of the Wyatt family, Bray Wyatt will face the Beast Incarnate, Brock Lesnar at Wrestlemania.
There were originally plans for John Cena to have a match with The Undertaker but an injury to Cena's shoulder derailed those plans. WWE were hoping to create major buzz with that match as it was "saved" for quite a long time to fill AT&T Stadium for Wretlemaia 32.
