Bray Wyatt vs. The Undertaker has been a long-rumored match for WrestleMania 31, and there is some speculation that the "Eater of Worlds" was talking about the "Deadman" in his promo on SmackDown this week.

Wyatt appeared in a segment on the WWE's special live edition of SmackDown on Thursday night from the XL Center in Hartford, Conn. and cut an eerily cryptic promo.

"What makes you smile? Is it spending time with loved ones? Is it money? Power? Perhaps it's a memory that you hold dear," Wyatt said. "Maybe something nostalgic from your childhood. But me? I'm different. I find enjoyment in the types of things that your mommy and daddy have shielded you from your entire life. [Laughs] I am not like you. I'm different. I'm legion amongst men. I fear nothing living or dead. So I ask you, what makes you smile? Cause after what transpires next, I promise it will be hard for you to ever smile again. Run!"

According to Wrestlingheadlines.com, there is a lot of speculation that Wyatt was referencing facing The Undertaker, especially when he mentioned he doesn't fear anything living or dead and by talking about fan's nostalgia and them never being able to smile again.

Rumors have surfaced over the last few months that a Wyatt vs. Undertaker match was tentatively penciled in for the "Show of Shows," but at last word 'Taker's status for WrestleMania 31 was still uncertain.

The Undertaker is a big question mark for this year's show after he was injured and lost The Streak to Brock Lesnar at WrestleMania XXX last year in New Orleans.

It is seen as a bad sign that the Royal Rumble passed by without the WWE being aware if the "Deadman" will appear at WrestleMania this year, but perhaps Wyatt's promo could be a sign of things to come or mean something else.

The only match announced for the "Show of Shows" thus far is Royal Rumble winner Roman Reigns vs. Brock Lesnar for the WWE World Heavyweight Championship. Triple H teased a big announcement for Monday Night RAW that could change the complexion of this match.

Other rumored bouts for WrestleMania 31 include John Cena vs. Rusev, Dolph Ziggler vs. Daniel Bryan, Triple H vs. Sting and a battle royal.
