Regarding The Undertaker’s status, there is still nothing definite. If there has been a final decision made, it is being kept very quiet.
As noted, Taker was not backstage at Monday’s RAW from Nashville, even though he was photographed at a Nashville Predators hockey game the night before. However, Taker reportedly did have a meeting with Vince McMahon while in town.
It’s said that Taker does not want to come back and have to fake his way through a mediocre match, which is why his status is up in the air. He had major shoulder and hip surgery over the past year which made it impossible for him to do any serious training for a long time. Taker couldn’t lift upper body because of shoulder rehab and couldn’t do lower body because of the hip rehab.
As of a few days ago, the internal word was that Taker is still “planned” to face CM Punk this year. People close to Taker believe that if he doesn’t do WrestleMania 29, then his career is not over and it would simply mean he didn’t have enough time to fully recover from everything. The expectation is that he would like to do WrestleMania 30 in 2014 and that the show could be built around his farewell since he will be 49 years old at that point.
