For what it's worth, there is a photo circulating that would appear to show Chris Jericho arriving at an aiport, which is claimed to have been taken at the Memphis Airport last night.
Jericho, naturally, wrote on twitter that it was photoshopped. I guess we'll see soon enough. I'm actually surprised in the sense that I would have figured they would send the private plane to keep him away from being seen at the airport and hide him out in a limo until his time to come out without letting anyone know he was in town, as they usually do for surprises.
We'll see tonight who the mystery man is. WWE officials are expecting a rating above a 3.0 due to the mystery man angle.
