‘The day started with the players who weren’t on the field, as tight end Dawson Knox, offensive linemen Spencer Brown and Sedrick Van Pran-Granger, and wide receiver Laviska Shenault did not practice. Bills head coach Sean McDermott did not elaborate on the timeline for any of the players to return to practice. Still, nobody with the Bills seemed overly concerned about the injuries being long-term issues. Bills general manager Brandon Beane shed some light on what led to Knox and Brown missing day one of camp.’
