#4. Chris Jericho's AEW contract could be due to expire, which would allow him to return to WWE
Chris Jericho could contractually return to WWE if his AEW contract expires in the near future.
While it's unclear exactly when Jericho's current deal will come to an end, it has been noted in several recent reports that it's due to expire at some point this year.
The former AEW Champion agreed to the stipulation of the match, so he obviously has a plan if the outcome isn't what fans are expecting. Several of these matches have happened in the past in WWE, and the wrestler in question actually left the company after losing the bout.
It's completely feasible that Jericho has agreed to have this match against MJF because he has been able to make the young heel a star, and Le Champion wants him to be the last person he wrestles in AEW.
If Jericho's contract is indeed set to expire, he could take some time away from the ring to heal and look after himself before then he makes a decision about his future. WWE will always be there for Jericho, and the door will always be open to someone at his level. For this reason, it's hard to rule out the former world champion returning to the place where he once reached new heights.
