On WWE Old School Raw, Dolph Ziggler had a one-on-one match against Ryback.
Unfortunately, it appears that Ziggler has suffered a concussion, his second over the course of the last few months. The concussion appears to be a result of a far too stiff clothesline by Ryback on Ziggler.
Dr. Chris Amann, who examined him in the ring after the match said Ziggler was having confusion and disorientation and after examining him backstage, confirmed he had a concussion.
