WWE Superstar The Undertaker hasn't been seen since WrestleMania 31 and while his in-ring future always remains a question mark, his contract is set to expire.

WWE Monday Night RAW Rumors and Preview

Wrestlingheadlines.com reports that there isn't much time left on The Undertaker's current WWE deal, though it is expected he'll sign something beyond a legends deal for his next pact with the company.

The Undertaker is expected to work with the WWE beyond his retirement, but his in-ring future remains up in the air for the time being and will likely become clearer come WrestleMania 32 season.

Hulk Hogan Returning To Ring at WrestleMania 32?

There were a lot of doubts surrounding the "Deadman" after WrestleMania XXX in 2013 in New Orleans when he lost The Streak to Brock Lesnar and suffered a legitimate injury during the contest.

Rumors surrounded 'Taker for months, but he eventually trained hard and returned to the ring for WrestleMania 31 on March 29 at Levi's Stadium in Santa Clara, Calif., where he defeated Bray Wyatt.

Now, The Undertaker's future is once again in question, but with WrestleMania 32 emanating from his home state of Texas, it's likely the Demon of Death Valley has another high-profile match in him at the "Show of Shows."

One notable name that 'Taker could clash with is fellow Texas native Sting, who made his WWE in-ring debut at WrestleMania 31in a loss to Triple H.

It had been rumored for years that Undertaker vs. Sting would happen when the WWE finally signed "The Vigilante" to a deal, however the company opted for a different route and paired 'Taker with Wyatt and Sting with Triple H.

It's possible the two wrestling legends will collide in an Icon vs. Icon match at AT&T Stadium in Texas next year as the WWE looks to set an attendance record, but it remains to be seen.

With The Undertaker's contract set to expire, a lot of speculation surrounds his next move.
