As a free agent, Rey Mysterio doesn't rule out a return to the WWE.
He left there in 2015 after being inactive for nearly a year due to injuries. Speaking to ESPN, he also says that he was looking to leave since his body was banged up and wanted to take time away from WWE to heal up.
"I told myself, once I started feeling aching and I was having hard times getting up from my bed in the morning when I woke up, it was gonna start getting close to that time [to quit]" he said. "I was feeling that right towards my end of the last year or so of WWE," Mysterio said. "It came to the point where I was feeling like that constantly. I didn't want to fall into another phase of taking either medication to ease my pain. I wanted to use the rest way to heal my body up. Believe it or not, the last two years, I don't think I've felt better."
He also reiterates that he doesn't belong to any company. He's been wrestling on the independent scene all over the world, including the US, Mexico and the UK.
"I'm not locked up to any company. I'm an independent contractor, as we say," Mysterio said. "I could go work wherever I want. That's the beautiful thing about being on this side of the fence. You don't have a commitment with only one company. You can go around and pretty much wrestle wherever you want. You can choose when you want your off-days to be. That was one of my main priorities when I left WWE."
Mysterio left the WWE knowing that he wanted to go back and finish up. He said that WWE's recent overtures, including a video speculating if he'd return this year (which you can see above) were interesting, but he hasn't been in contact with them. Still, he'd like a chance to go back there and say his goodbyes.
"I would definitely love to go back and finish up" he told ESPN. "Whether it's one year or whatever the case might be. Whether it's a farewell. I owe a lot to that company. That company gave me such an amazing opportunity, and I took advantage of every single moment I was with WWE to the fullest. I wouldn't want to just be remembered as 'Oh, man, he never re-signed and he never came back.' I would definitely love to come back and do a last run and say goodbye to my WWE fans. Tell them goodbye in a proper way."
Mysterio most recently was a part of the Arolucha tapings, and looks like he will be working with them going forward, though he's not under a binding contract there.
