The former WWE champion returning tonight on Raw is Chris Jericho. The nature of his role, I have not confirmed.
Jericho is also tentatively slated to appear on tomorrow's Smackdown taping in Newark, NJ.
In other Jericho news, he recently launched a campaign for a Jericho fan stricken with terminal cancer. For complete details on how you can support that campaign (and you should), click here.
