WWE will not have John Cena return until the Hell in a Cell pay-per-view.
Cena will return at the pay-per-view, and then appear on the RAW the night after the pay-per-view.
We're told Cena will be on both RAW and SmackDown between Hell in a Cell and Survivor Series. Following that, he will be on the road doing house shows, and only be working RAW tapings.
