As the Buffalo Bills prepare to attempt to extend their record to 5-0, they might have to do it without three starters on defense.

Cornerback Terrence McGee is listed as doubtful, due to a knee injury.  Defensive tackle Marcus Stroud (shoulder) and defensive end Aaron Schobel (foot) are questionable.

For the Cardinals, receiver Anquan Boldin is out due to the head injury suffered against the Jets, when he took a Madden-style kill shot from Eric Smith.  Defensive end Bertran Berry (groin) is doubtful.
