WWE has listed and advertised Rey Mysterio to return next Tuesday at the Smackdown taping. Smackdown on Tuesday, July 17th is set to be taped in San Diego, California. This is the home of Rey Mysterio.
It is unclear if Mysterio will be at WWE Money in the Bank or at the following night's WWE Raw. He is not being advertised for either of those events, but plans usually change heading into a Pay Per View.
Mysterio has not been seen on television since late 2011, where he presented an award at the WWE Slammy Awards Raw. He was injured in a house show match against Alberto Del Rio. Later, he was suspended for 60 days for his second Wellness Policy Violation. He has been clear to return since June 26th.
