Terry Funk's twitter account (which is run by someone else) posted that Funk was doing okay. He wanted to wish Moxley and Omega the best in their exploding barbed wire deathmatch.

“Just talked to Mr. Funk & he’s doing okay. He just wanted to wish @JonMoxley & @KennyOmegamanX the best of luck in their exploding barbed wire match. He says the match is a good way for @aew to wake up Vince with a good kick in his ass. He wants you to know he’s pulling for you!”

Terry Funk has done many of these matches throughout his career as a pro wrestler.
