According to a report by Mike Johnson, Ryback is said to be under fire after Dolph Ziggler suffered a concussion during a match taped last night in Baltimore for Superstars. Ziggler suffered the concussion after he took what was described as a stiff clothesline from Ryback during the match. Ryback has been critcized in the past for being “reckless” in the ring and is something WWE officials are very aware of. Ziggler’s concussion is believed to be very serious and is the second concussion he has suffered since May 2013.
