According to a WWE source, Chris Jericho’s representatives recently negotiated with WWE and extended his current deal. The original deal was only for him to return for six months. The sources notes that Jericho has extended his current WWE contract by several months. He'll be a “full time” talent with WWE through the summer.
Jericho recently revealed that he had signed a deal with Fozzy which would feature a concert tour during the summer. There is no word on how the WWE deal may affect that. Jericho has been joking on Twitter that this is his latest “this tour of duty” with WWE.
