Dave Meltzer of the Observer is reporting that Rey Mysterio is currently out injured and was originally supposed to be part of the Smackdown World Cup tournament.

Mysterio was spotted wearing a walking boot backstage at the Smackdown tapings this past Friday and while the injury doesn’t seem a long-term one, he was not going to make it in the tournament and was replaced by Mustafa Ali.

It’s unknown when Mysterio suffered the injury but the former champion last wrestled during a non-televised live event in Mexico on October 30.

Mysterio recently moved to the Smackdown brand from Raw to be separated from his son Dominik for storyline reasons.
