There has been a lot of speculation ever since The Undertaker lost to Brock Lesnar at WrestleMania XXX in April that he may have wrestled in his last match following the end of The Streak and him sustaining an injury, but it appears as though the "Dead Man" is being advertised for WrestleMania 31.

The Undertaker lost at WrestleMania for the first time ever on April 6 at the Mercedes-Benz Superdome in New Orleans when Lesnar pinned him to the mat, and there have been a lot of rumors that 'Taker may not return to compete at WrestleMania 31.

With The Streak over and 'Taker getting injured, it appeared as though he may call it a career, but the WWE has him featured on trucks advertising WrestleMania 31 at Levi's Stadium in Santa Clara, Calif. along with injured Superstar Roman Reigns and WWE Diva AJ Lee.

While this doesn't mean The Undertaker will wrestle, it at least makes it appear as though the WWE is banking on him making some sort of appearance at the Show of Shows next spring. There have been reports that those close to 'Taker believe that he will not compete this year at WrestleMania 31.

There have been rumors that Steve "Sting" Borden would face 'Taker at the biggest event of the year on March 29, 2015, but with 'Taker's status up in the air it remains to be seen.

Sting has said in interviews he'd like to face 'Taker at WrestleMania, but also indicated that he wasn't sure if The Undertaker would be willing to work a match now that The Streak is over. Sting also said he'd be willing to face Triple H as well.

There were rumors going around that The Undertaker's health was taking downward turn after Limp Bizkit frontman Fred Durst told the crowd at a recent show that 'Taker wasn't doing well, but 'Taker's wife and former WWE Diva Michelle McCool recently dispelled the rumors on Instagram.

The Undertaker appears to be doing better than initial reports indicated after WrestleMania XXX as he and McCool appeared in the CC4C Micro Marathon 4 Inspiration Sunday, which is a 2.62 mile family fun run around the Hill Country Galleria in Bee Cave, TX to raise money for children suffering from rare and undiagnosed illnesses, according to Wrestlingheadlines.com.
