The Cowboys confirmed Roy Williams' negative x-ray in an email this morning. There was no fracture to his shoulder. They will continue to evaluate him on a day to day basis with a shoulder contusion, which is a fancy word for a bruise.
However it is still unlikely that Williams will play against the 49ers on Saturday for precautionary reasons. If he does sit then look for him miss the preseason final against the Vikings on Thursday and return for the regular season opener against the Tampa Bay Buccaneers.
