Vader reportedly refused to work a live event in Germany. The promotion was wXw and this story is currently being followed closely by yours truly.
Here is part of a statement released by the promotion:
This morning, when Terry Funk, Chris Masters and Steve Corino were about to get into their booked cab to the airport, Big Van Vader refused to leave his hotel room. Various attempts by our English partner promoter, Masters and the end Terry Funk himself to convince Vader otherwise proved fruitless. After Vader already refused to wrestle his agreed-upon match last night, today he decided that, despite already having received an advance payment, the fact that there is a sold out meet & greet session for him and the fact that we promoted the event around him, he would not fulfill his contractual obligations.
Author's Note: WrestlingNewsWorld.com writers Jesse & Kendra saw Vader at a live event in Maine a month ago. They both reported how standoffish he was and refused to talk to most fans. Both Kendra and Jesse were in front of him and tried exchanging pleasantries. The condition and mindset of Vader is unknown at this time. We will follow this and have updates here at WrestlingNewsWorld.com.
