Bills DT Kyle Williams was back practicing after missing Wednesday’s practice. John McCargo however, is still not practicing with a strained calf. Shawn Nelson, who was limited Wednesday, had his pads on so his shoulder appears as though it might be ready for contact. Roscoe Parrish sat out for a portion of the individual drills at the beginning of practice. We’ll get an update from head coach Dick Jauron as to why after practice today. LT Demetrius Bell was not practicing again on Thursday due to his groin injury. Jonathan Scott has been taking reps at left tackle in his absence with Kirk Chambers at right tackle. Also not practicing were Donte Whitner, Bryan Scott and Leodis McKelvin.
