WWE superstar Dolph Ziggler suffered a concussion on the WWE Superstars tapings prior to last night’s “Old School” edition of WWE RAW during his match with Ryback.

The concussion will keep Ziggler out of action until he passes the company’s testing system and is cleared to return to the ring. Ziggler suffered a concussion last year that kept him out of action for some time and ended a brief run as the World Heavyweight Champion.
