Jon Moxley faced Rey Fenix at AEW Dynamite: Grand Slam and lost the AEW International Championship. During the match, Moxley sustained a concussion, leading to a decision being made for Fenix to go over.
As far as solutions to spotting a concussion in a wrestling match go, Moxley suggested a red button that the doctor can push to end the match.
“As soon as the doctor sees a sign of somebody being concussed, he just hits the f—ing red button. Boom, this is over. No matter how much time is left. No matter if it’s on live TV. It’s just over, and you figure it out from there,” Moxley told The Messenger.
