-- Santino Marella has been out of in-ring action as of late because he's rehabbing a chronic neck injury. There is no word on when he'll be returning.
-- Christian and Sheamus are both ready to return and several people within WWE say they wouldn't be surprised to see them in the Royal Rumble match. Chris Jericho is also a possibility but that's not confirmed. He will be in the area for an event so it can't be ruled out. Jake Roberts was also being talked about but nothing is confirmed on that front either.
