The clock is ticking on a potential return for The Undertaker in WWE. The road to Wrestlemania 31 has begun, following the 2015 Royal Rumble, and the Phenom hasn’t made an appearance since Brock Lesnar broke his undefeated WrestleMania streak. While nothing is official, it appears more likely than not that The Undertaker will have a match at this year’s event.

According to the Wrestling Observer, WWE officials believe The Undertaker will wrestle at WrestleMania 31. There has been no announcement, but it’s possible that some in the company already know The Undertaker’s plans.

The Undertaker’s WrestleMania status has been a mystery in each of the last few years. In 2013, he made a surprise appearance at a house show in late February, and went on to fight CM Punk a few weeks later. Last year, he appeared on “Monday Night Raw” after the Elimination Chamber pay-per-view, beginning his program with Lesnar.

After the ending of the Streak, though, The Undertaker’s return is in more doubt than ever. Not only did he finally lose at WrestleMania, but he was badly injured at the event. The Undertaker suffered a concussion and was immediately rushed to the hospital, after his loss to Lesnar.

The Undertaker has been injured after previous WrestleMania’s. He reportedly needed surgery on his shoulder and hip, following his match with Triple H at WrestleMania 28.

Bray Wyatt appears to be the most likely opponent for The Undertaker, following the Royal Rumble. The Undertaker vs. Sting, a match that many fans have hoped to see for years, is almost certainly off the table, since Sting is headed for a match with Triple H in March. A rematch with Lesnar would make sense, but the champ is set to face Roman Reigns in a WWE World Heavyweight Championship match.

If The Undertaker doesn’t return at WrestleMania 31, it doesn’t necessarily mean he’s done wrestling in WWE for good. He could always come back at WrestleMania 32, which will be held in Dallas in front of a crowd of approximately 100,000 fans.

There has been some speculation that The Undertaker could headline the 2015 WWE Hall of Fame class, though that’s not likely to happen if he has a match the next night. Randy Savage and Arnold Schwarzenegger have already been confirmed as inductees for this year.
