Ever since The Undertaker lost The Streak at WrestleMania XXX to Brock Lesnar, there has been speculation that he will not appear at WrestleMania 31 and that he may even retire after getting injured during the match. It appears as though 'Taker is questionable for an appearance at the biggest show of the year next March.

For the last few years, The Undertaker has had about one match a year while making appearances at WrestleMania in defense of The Streak, but now that his record at the show is blemished following Lesnar's win in April in New Orleans, it is doubtful he'll return in March for WrestleMania 31 in the Bay Area.

According to Wrestlingheadlines.com, The Undertaker has returned to the gym to workout but is still in rough shape coming out of the match with Lesnar. The Undertaker has reportedly told some people close to him that he isn't looking good for a match at WrestleMania 31.

'Taker suffered a concussion at the biggest event of the year and has been really banged up for the last three months, casting doubt over whether or not he'll wrestle again. There is no definitive confirmation on whether or not he will in fact return and his status is very much up in the air despite him saying it is doubtful he will return. The Undertaker hasn't completely shut the door on a comeback in 2015.

There were rumors that once the WWE finally signs Sting to a deal the company was hoping to have him battle 'Taker in one final match for both men in an epic showdown that has been talked about for years, but some of the allure may have been taken away now that The Streak is over.

Sting wanted to work with 'Taker at this past year's WrestleMania, but the WWE opted to go in the direction of having Lesnar take him on and end The Streak. After 'Taker lost and was subsequently injured, speculation began that he may choose to retire now that he's aging and his lengthy career has taken a toll on his body.

It remains to be seen if The Undertaker will comeback for next year's event and if Sting would be a chosen opponent for him, but now that he is 21-1 at WrestleMania, the sense of urgency for a return may not be there.
