WWE has posted another update on Dolph Ziggler after he suffered a concussion at Monday’s Superstars taping in a match with Ryback. WWE’s Dr. Amann noted that Ziggler saw a neuropsychologist on Thursday and had ImPACT testing performed as well as balance testing. All of those tests appear to be equivocal to baseline and within normal limits. Ziggler’s symptoms have improved significantly since Monday night. They are having him rest more and when he is asymptomatic, he will begin doing light cardio exercises and if that goes OK, WWE doctors will proceed with their “exertional protocol.”
