In a report from PWInsider, the Undertaker is set to be in a match at WrestleMania 31, and that match should be against Sting.

PWInsider previously reported that the Sting debut was to set the stage for an eventual Undertaker-Sting showdown.

But with the good news of the Undertaker vs Sting match at WrestleMania31 being confirmed, there are some rumors that this would be Undertaker's last match with the WWE.

"The Undertaker could be inducted into the WWE Hall of Fame in 2015 should WrestleMania 31 be his final in-ring appearance. There has been talk for years that Undertaker would be inducted into the Hall of Fame following WrestleMania 32, which takes place Cowboys Stadium and is expected to set an all-time attendance record."
