There has been no official announcement from WWE about Jericho's return, so take it as a rumor for now. WWE's page for the event has John Cena, Daniel Bryan, Randy Orton and The Big Show listed for the show. The arena's website does not currently have any names listed for the event.
The only reference Jericho has made about a WWE return in recent days was on Twitter. When asked what number he was given for this year's Royal Rumble, Jericho joked, "31."
