The following was reported by Mike Johnson from PWInsider.com:
"The Undertaker was telling those backstage after his match with Bray Wyatt that
he felt great and intended to work next year's Wrestlemania in Dallas, Texas.
Given how strong Taker looked in the ring and how well he was moving around
before and after the show, a lot of people noted that he really must have been
concussed far worse than anyone really understood the year before against Brock
Undertaker shared a locker room backstage with Sting and the two actually
shared the same flight back to Texas. There was a lot of "if we do this" talk
between the two about a potential match. The original idea when Sting came in
was to eventually lead to the Undertaker bout at a Wrestlemania, although WWE
management has cooled on long-term plans for the former WCW World champion."
