The following was issued on WWE.com on Wednesday:
"World Heavyweight Champion Dolph Ziggler suffered a concussion at Tuesday night’s SmackDown taping at N.C. State when he interfered in Big E Langston's bout with Jack Swagger. According to WWE physician Dr. Michael Sampson, Ziggler was injured during the early part of the fracas after a blow to the face. A post-match examination by WWE medical staff confirmed the injury.
“He [was] having some memory difficulties and a bit of a headache … he definitely has a concussion,” said Sampson. “We’re checking him out, and going to be doing neuropsychological testing and just keep it monitored.”
Though clinically Ziggler’s concussion was confirmed, the tests – which should yield results within the next couple of days – will provide WWE medical officials with a “baseline” from which to monitor The Showoff’s clinical and neuropsychological progress as time passes.
