Returns: Edge, Y2J, Cena & Lashley
Former World Heavyweight Champion, Edge, has been out of WWE action for several months now. Edge is pictured on the Survivor Series posters and is on the recent television ads, shown using a chainsaw. This would seem to indicate Edge is coming back at Survivor Series, and may get involved in a match, perhaps the Michaels vs. Orton match. Orton has the stipulation he can't get intentionally DQ'd. Edge may also decide to interfere in the traditional Survivor Series match which Kane is a participant in, since Kane is considered "responsible" for Edge's injury. This is all speculation at the moment.
Chris Jericho's return to WWE continues to be an enigma and there really hasn't been a date put on it by any wrestling sources. A fan commented that the recent commercials may indicate Jericho will return to the Monday Raw on November 19th, one night after Survivor Series. This could make sense, as Shawn Michaels also made a return to Raw and did so the night following a Pay Per View. Read more about one interpretation of the Y2J ads.
Bobby Lashley has been out for a while now, since hurting his shoulder at the Backlash Pay Per View. He underwent surgery in June of 2006 to repair the shoulder and is now healing up. There hasn't been any recent indication of his return status. On an IGN.com interview in late October, they spoke to Lashley and Torrie Wilson regarding the Smackdown vs. Raw video game. During the interview Lashley said with regards to injury he goes home to his mailbox, gets his check, then rubs it on the injury and "magically all the pain goes away". Watch the IGN interview here.
As for John Cena, he's on the shelf for a bit recovering from a torn pectoral muscle suffered against Mr. Kennedy on Raw. In his recent interview with CNN (the unedited version), Cena says he will most likely take 9-12 months for a full recovery. Cena says for now his workout consists of gripping a golf club just to keep his arm in motion. Cena also said he's not allowed to sweat as the surgery wound is still fresh and needs to heal.
