‘Buffalo’s ailing defense has lost top cornerback Tre’Davious White for the season, and Christian Benford, the other starting corner, is dealing with a shoulder injury that forced him to miss Sunday’s game in London. Nickel defender Taron Johnson banged his knee on the turf in the loss to the Jaguars, and second-year cornerback Kaiir Elam was benched in the fourth quarter. On top of that, All-Pro linebacker Matt Milano (leg) and starting defensive tackle DaQuan Jones (chest) need surgery and are out indefinitely.’
