In what may turn out to be a bigger story later on, Undertaker has removed references to "WWE" on his Twitter profile, while also including an email address for promoters to book him for indie appearances. You can find his profile HERE.
Furthermore, at the end of April, Taker is set to make his first non-WWE appearance as Undertaker for "For The Love of Wrestling" as seen below where he will be there alongside other former WWE stars and Hall-of-Famers, such as Ric Flair, Lita, Kevin Nash, more.
The Deadman's first ever appearance outside of the WWE, and we are very proud to be the company bringing him to you.

He is also scheduled for another tour at the end of April and beginning of May which would seem to be occurring at the same time as WWE's next visit to Saudi Arabia so its fair to question whether he will be a part of that event. While this all could mean nothing in the end, it is interesting to note that these developments have taken place only after recent news suggested that Taker is not scheduled for any storylines or a match at WrestleMania.
