-- Chris Jericho's deal to work the Royal Rumble is believed to have been made when the company contacted him regarding a potential appearance on the 1,000th episode of RAW. Jericho was kept hidden in a bus outside the arena until his entrance; no word on his long-term contract status.
-- There were plans to use Mark Henry, Carlito and Shelton Benjamin at the Rumble but it didn't happen. This was the first PPV that Henry has been brought in for since he was hurt. There had been discussion of using Carlito since he visited backstage at the 1,000th RAW, but certain people soured on him when he began slamming CM Punk online.
-- Ted DiBiase was backstage at the show; he is expected to return from injury soon. Chris Masters was also there visiting but was not used.
