Mysterio and WWE have been at odds for some time regarding his contractual status. There's been talk for some time that he would be released before the end of this month.
Mysterio signed with WWE in 2002 after a five year run with WCW. Over the course of his WWE career, he held the WWE and World championships and became one of the most popular wrestlers in the company's history, especially among Latin American fans and children.
Lucha Underground has made several hints about someone that "fans know well" introducing Konnan to Prince Puma with Mysterio being the most likely candidate. If Mysterio ends up there, it reunites him with not only longtime friend Konnan but former WWE rival Alberto El Patron (fka Del Rio).
We have reached out to WWE for confirmation.
