According to a report by Mike Johnson, current WWE World Heavyweight Champion Dolph Ziggler is not at tonight’s RAW taping in Tulsa and he is not scheduled to work the Extreme Rules PPV this Sunday. Ziggler suffered a concussion at the Smackdown taping last Tuesday and was later diagnosed with retrograde amnesia. He was scheduled to undergo Impact testing to determine if he would be healthy enough to work the PPV this Sunday in St. Louis. The belief is that the company will go forward with a #1 contendership match at Extreme Rules to determine Ziggler’s next challenger.
