As it stands right now, Matt Cardona is not currently under a long term deal with All Elite Wrestling.
Cardona made his debut for AEW at Wednesday night's tapings, making the save for Arn Anderson after Dark Order members Alex Reynolds and John Silver took out both Cody Rhodes, and Cody's TNT title match opponent Warhorse. The two had Anderson cornered when Cardona hit the ring and dispatched of both, at one point using his standard Ruff Ryder finisher (now known as "Radio Silence").
Cardona is set to team with Cody to face Reynolds and Silver on next week's episode of Dynamite.
The former Zack Ryder was released from WWE in mid-April, after 13 years with the company. His longtime tag team partner Brian Myers (Curt Hawkins) was released the same day, and has since turned up in Impact Wrestling.
