The Wrestling Observer is reporting that the word going around among numerous WWE talents overseas is that The Undertaker decided against going on the European tour due to the recent terrorist bombings in Belgium and France. Of course, take this news with a grain of salt.
It should be noted that ‘Taker was pulled from several live events in the UK as well, which were the final two shows he was scheduled to appear at. Also, The Undertaker has a history of back issues and it’s a very long flight overseas.
Whatever the case may be, we can confirm that he went back and forth as to whether or not to make his European tour appearances and that’s the reason WWE pulled him from one or two events at a time. He was still debating on working the UK dates but obviously wound up pulling out of those as well. That may have been more due to the back issues & long flight though.
