According to a report from the Wrestling Observer Newsletter, Arn Anderson’s son (Brock Anderson) and Taz’s son (Hook) have been working matches prior to the AEW TV tapings as they try to train as much as possible.
Prior to anything being taped, they work in the ring during the afternoon hours and veterans like Arn, Jake Roberts, Dustin Rhodes and others help them out. Tully Blanchard has also been spotted joining in at times. The trainers tell them what went right and how to improve. They were both trained at the Nightmare Factory.
