It looks like the much anticipated Sting vs Undertaker match would be moved to WrestleMania 32 and Undertaker would face Bray Wyatt at WrestleMania 31.

Bleacher Report has reported that most of WrestleMania 31's matches have been locked-in and it is set in stone that Sting would face Triple H while the Undertaker would face Bray Wyatt at WrestleMania 31.

Meanwhile, Inquisitr reported that Undertaker's WWE return can happen on late February to March:

"It likely won't be until after Fast Lane on February 22 that Undertaker reappears on television. This way, he won't have to be on television much, and there will be a month to build up a program."

But why didn't the Undertaker vs Sting match materialize on WrestleMania 31?

ProWrestlingSmarks has reported that WWE can't put Sting vs Undertaker on WrestleMania 31 because they can't have a scenario where either Sting loses his first WWE match/First WWE PPV or the Undertaker loses twice in a row at WrestleMania. Moving their match to WrestleMania 32 would alleviate this problem.

Meanwhile, as for the reason the Undertaker facing Bray Wyatt in WrestleMania 31, Bleacher Report says:
"Per Wrestling Inc., Jim Ross recently said that Wyatt's full potential has still not yet been tapped, and he needs a strong and established wrestler to bring that out in him. That's where the Undertaker comes in, and why this match would be perfect."

What do you think? Should the Sting vs Undertaker match take place on WrestleMania 31 or is WWE right that it should be moved to WrestleMania 32? Sound off in the comments below!
