One scenario where AJ and Wilder may fight, is if Tyson beats AJ. This fight may happen this time next year if not sooner.
In that scenario Tyson would be undisputed Champ, with neither AJ or Wilder having any titles. They would then fight for the right to face Fury once again.
Again in that scenario, Tyson may retire after becoming undisputed. But I'd say stick around until both AJ and Wilder are actually in the ring together and then announce retirement to make the titles vacant, otherwise the AJ and wilder fight will not happen.
