As we exclusively reported several weeks ago, Rey Mysterio has re-signed with the WWE and is still pencilled in to be a SmackDown talent.
Rey has been under a WWE contract since August 1st, which is why he was pulled from a Northwest Wrestling show on August 24th.
Rey was pulled from the show, as he was originally set to debut on the SmackDown after SummerSlam- as revealed by our sources. However, these plans were changed, and his return to TV is currently being held off. He is likely to be saved for either the SmackDown Season Premier next month or the SmackDown 1000 show. Regardless of him not appearing on TV yet, Mysterio did re-sign with the WWE several weeks ago and is under an actual performers contract, not just a 2K Games deal.
