Sin Cara has signed a new deal with WWE, according to PWInsider. The new deal is for for 3 years. 

Sin Cara signed the new deal several weeks back as he had been working under the terms of an extension from his previous contract.

He's going to make a return to SmackDown Live soon, and has been off WWE programming to recover from a knee surgery he got done in August 2018. He was backstage last week for SmackDown Live and has been training at WWE's Performance Center.
