‘Wide receiver Joshua Palmer (ankle) and linebacker Terrel Bernard (elbow) were unable to practice Wednesday. The Bills’ starting left tackle, Dion Dawkins, rejoined the team for the walk-through as a limited participant, but he’s still in concussion protocol, coach Sean McDermott told reporters. Bosa is considered week to week, McDermott added, which means the edge rusher could miss anywhere from one to four or five weeks. It’s too soon for the team to determine the severity of the hamstring injury.’
