ORCHARD PARK, N.Y. (AP) — The Buffalo Bills will be missing four defensive regulars — and potentially more — for their AFC East showdown at the Miami Dolphins on Sunday. Safety Micah Hyde, cornerback Dane Jackson, tackle Ed Oliver and backup tackle Jordan Phillips have already been ruled out from playing. In the meantime, starting safety Jordan Poyer and tackle Tim Settle are among five players listed as questionable after practicing on a limited basis. The 2-0 Bills will most certainly be thin in their secondary even if Poyer is available with rookie cornerbacks Christian Benford and Kaiir Elam in line to start.
