Jericho has been denying a WWE return, which means that this could be another return accidentally leaked.
It should be noted that this could be a one-time deal as Winnipeg is Chris Jericho's hometown. We hope to have more shortly.
UPDATE: There has been more local advertising of Chris Jericho for the March house show in Winnipeg, Manitoba. One reader noted that there have been digital ads in elevators in "at least two buildings in Toronto" over the past week advertising Jericho for the show.
UPDATE x 2: According to WWE sources, that story was a mistake and they are asking the newspaper to run a correction. Of course, this could be WWE's way of trying to cover their mistake as they want to keep things a secret similar to what they wanted to do with Batista. We shall see.
