Chris Jericho's representatives have negotiated an extension on his current WWE deal, which was originally for six months. The challenger for CM Punk's WWE Championship at WrestleMania has extended his contract for several months, and will be "full time" in WWE through the summer.
It is not known what happens to the Fozzy concert tour that was originally scheduled for the summer, but Jericho's tenure in WWE for what he has been jokingly calling "this tour of duty" has been confirmed as "extended," which means he will either continue feuding with CM Punk or be a major part of the WWE draft to help the SmackDown brand after WrestleMania.
