WWE Reportedly Blocking AEW Stars From Appearances?

WWE is reportedly trying to prevent events from booking AEW starts that also have WWE Superstars booked.

Dave Meltzer of Wrestling Observer Newsletter noted the following:

The convention guys were basically told you cannot book anyone from AEW. That’s one of the rules now that if you book a WWE guy anywhere you know baseball game, autograph signing, Wizard World — that nobody from AEW is allowed. That’s just their rule."
