Cowboys receiver Roy Williams was not at practice during the 25 minutes the media was allowed to watch. He did not appear on Wednesday's injury report and practiced fully Wednesday.
QB Tony Romo (left clavicle), LG Kyle Kosier (right Achilles'), guard Montrae Holland (groin) and DE Jason Hatcher (groin) sat out Thursday. Kosier worked on the side during practice. Holland said Wednesday he has been doing "everything I can do" to get healed. Rookie free agent Phil Costa is taking all of the snaps at left guard with Kosier and Holland hurting.
