Dolph Ziggler's concussion is legitimate and occurred during a segment involving a ladder with Alberto Del Rio and Jack Swagger following a bout taped for this week's Smackdown.
We don't have the specific details on which spot the concussion occurred but Swagger got heat Monday night for being reckless with a ladder on Raw. Both WWE officials and Del Rio were vocal in that Swagger could have hurt someone.
There has not been a decision made on what to do at Extreme Rules but Ziggler will not be medically cleared until he passes ImPACT-Testing.
We actually heard early Wednesday morning that Ziggler was examined backstage at the Smackdown taping in Raleigh, North Carolina although our source was unaware if what they were doing was part of a storyline. Once WWE posted the story on dot com, we were able to verify the legitimacy of the injury.
