Mysterio was holding his left shoulder after the match and trainers checked on him when he got backstage.
PWInsider is reporting that the belief is that Mysterio has a separated shoulder.
If that is indeed the case then WWE may need to figure out what to do with the United States Championship. The plan was for Mysterio’s feud to continue with Joe as they introduced Dominick into storylines.
The feud will need to be put on hold if the injury news proves to be accurate.
