While it was possible that Cabana's appearance could've been a one-off (the event was in his hometown of Chicago), it turns out that the 21-year veteran has signed with the promotion.
Tony Khan confirmed during the post-show media scrum that Cabana now works for AEW.
"Colt is working here," Khan told the media. "He does a variety of things. He already started as an announcer, and now he's gonna be working as a wrestler.
"I could see Colt wrestling for us on a regular basis. He can chip in as a commentator and also as a coach. He's a valuable mind. He's signed here. He can work, at my discretion, Colt can work other places."
Cabana recently wrestled for the likes of NJPW and the NWA. He previously did a stint as commentator on AEW Dark back in December.
