As previously reported, WWE Superstar Rey Mysterio made his official television return at Monday's "RAW Country" show in Nashville, Tennessee. Mysterio returned in the 12-main main-event to help the babyfaces even the score during a heel beatdown spot after the conclusion of the match.

While it was widely speculated following the show, it has since been made official -- Mysterio will be the "mystery partner" in the traditional elimination match at the WWE Survivor Series pay-per-view. The match will feature The Usos, Goldust, Cody Rhodes and Rey Mysterio vs. The Shield and The Real Americans.

UPDATE: WWE.com has confirmed that Rey Mysterio will be the fifth member of the team led by WWE Tag Team Champions Cody Rhodes & Goldust as they team up with the Usos to face the Shield and the Real Americans in a 10-Man Traditional Survivor Series Elimination Tag Team Match this Sunday at the Survivor Series PPV in Boston, Massachusetts.
