PWInsider.com is reporting that The Undertaker is backstage at RAW today and will be appearing on the show tonight to kickstart his WrestleMania program.
Taker had been touch-and-go regarding his involvement at WrestleMania and it was only just very recently that it was decided that he would be a part of the show this year. He is rumored to be facing off CM Punk at WrestleMania 29, hoping to keep his streak alive by going 21-0.
The Undertaker has been off WWE television since the RAW 1000 episode back in July of last year where he made an appearance coming to help Kane. He wrestled at a non-televised live WWE event on February 23 in Waco, Texas, making a surprise appearance in a tag team match with Sheamus against Damien Sandow and Wade Barrett.
