Possible Spoilers: Rey Mysterio's Future, Batista, & More
PWInsider is reporting that Rey Mysterio has been working through a really bad knee injury for a while now. It's said that he will need surgery, but doesn t want to take any time off because this is his time on top in the company and the Smackdown roster is pretty light right now.
It's likely that WWE will wait until Batista comes back to Smackdown before they take the title off Rey.
Whenever the title does come off Rey, he will likely get checked out by a doctor and scheduled for surgery.
