Rey Mysterio is the latest high-profile name expected to take part in the 50-man Greatest Royal Rumble match from Jeddah, Saudi Arabia later this month.

Mysterio made a surprise return to WWE back in January when he entered the Royal Rumble match. Since then, it’s been widely reported that the former World Champion was in talks bout a return to the WWE roster. During an early March appearance for Northeast Wrestling, Mysterio suffered a biceps injury which has kept him out of action ever since.

Word broke last week that Mysterio will be returning to a WWE ring at the Greatest Royal Rumble event, which led fans to wonder if this would be another one-off appearance or if Mysterio would be joining the WWE roster on a more regular basis. The Wrestling Observer Newsletter now reports that Mysterio and WWE are in talks about working together in a greater capacity. For now, the Greatest Royal Rumble appearance will be another one-shot deal.

In the event that Mysterio and WWE reach a new deal, it likely would not take effect until the summer, since Mysterio has commitments with New Japan Pro Wrestling and other independent promotions that he first needs to fulfill.

WWE has yet to confirm the news of Rey Mysterio competing at the Greatest Royal Rumble event on 4/27.
