After Joey Bosa missed almost all of the spring with a sore calf, offensive lineman Sedrick Van Pran-Granger has been sidelined at the start of camp with a calf injury, and now linebacker Dorian Williams is down with that same ailment.

Joey Bosa got most of Thursday off as the Bills are making sure they protect him as best they can from injury.

Coach Sean McDermott said tight end Dawson Knox is dealing with a hamstring injury, offensive tackle Spencer Brown still has lingering back problems, wide receiver Laviska Shenault has a lower leg strain, and offensive lineman Sedrick Van Pran-Granger has a calf injury.
