WWE Universe was delighted after King of Luchadors- Rey Mysterio signed a two year deal with WWE in September 2018. However, reports suggest that the veteran wrestler might be leaving WWE in coming months. He has an out-clause in his contract at the eighteen month mark and if he decides to take that out-clause then he could be exit WWE just before WrestleMania 36.
Mysterio was out from in ring action due to injury this year and WWE might look to extend his contract to cover up the time he lost due to injury. If they manage to convince him to extend the contract, Mysterio is likely to make Wrestlemania next year without having to execute an out-clause.
It will be interesting to see if Rey finishes his in ring career in WWE or he will move to AEW.
