From WWE.com:
Dolph Ziggler has suffered a concussion during tonight’s taping of “WWE Superstars” while competing in a match against Ryback.
“Unfortunately Dolph sustained a concussion during his match on the clothesline given to him by Ryback,” said WWE physician Dr. Chris Amann. “We were able to evaluate him in the ring; he was having some confusion and disorientation. We took him back to the training room and confirmed a concussion. He’s currently feeling better but we’ll proceed with ImPACT testing and further evaluation to determine when we can get him back in the ring.”
