‘Cornerback Taron Johnson, who is in the league’s concussion protocol, was also limited, while safety Jaquan Johnson was out again with an ankle injury. Johnson is the only Bills player on the active roster who did not practice. Wide receiver John Brown was designated to return from I.R., but is not required to be listed on the injury report since he is still officially on Injure Reserve. The Bills can activate him to play this weekend if they choose.’
