Shelton Benjamin announced today on Twitter that he needs surgery to repair a torn rotator cuff and that his WWE debut will be on hold.
Going off of Benjamin’s tweets, it sounds like this is an injury that the WWE discovered. Benjamin is someone who could have fit in nicely on Smackdown. He could probably have a good match with anyone on the roster given his athletic ability. Benjamin’s experience would have helped fill a veteran role on the Smackdown brand.
I would expect Benjamin to still have a spot waiting for him on Smackdown once he returns from injury. General recovery time for rotator cuff surgery is 6 months.
