Dolph Ziggler suffered a concussion at the Smackdown taping last week. It happened when Swagger kicked him in the head when he bent down to pick up a ladder that was in the ring. Reports say that Ziggler had memory loss from it and doesn't remember anything that happened on monday or tuesday of last week. WWE is working on another plan for his title match at the PPV next week if he's not cleared to compete.
If Dolph can't go, maybe they can put Mark Henry or Antonio Cesaro in there instead. We might actually get an interesting world heavyweight champ if one of them are involved.
