As noted earlier, WWE has signed Chris Jericho to a short-term deal. Jericho will be working full-time through WrestleMania 29, according to multiple sources. Following a feud with Dolph Ziggler, Jericho is scheduled to turn heel. Backstage talk at the Royal Rumble was that Jericho will face Ryback at WrestleMania 29 but that's not confirmed.
Woah! I thought this was just a one-off appearance considering all the workload he has with the new tv show and such. Good for Jericho. Now we have The Rock, Triple H, Brock Lesnar, CM Punk, The Undertaker, Alberto Del Rio, Dolph Ziggler, Ryback, John Cena, and a couple others trying to find a way on the card.
