Bills’ offensive tackle depth thinned further with Tommy Doyle sustaining season-ending injury

Buffalo Bills backup offensive tackle Tommy Doyle sustained what coach Sean McDermott on Sunday described as a season-ending injury, further depleting the team’s thin depth at the position. McDermott wouldn’t specify the nature of the injury, a day after Doyle was hurt early in the third quarter of a 27-15 preseason loss at Pittsburgh. Doyle has appeared in 12 games over his first two seasons.
