Overview
- Head coach Sean McDermott said Cook did not practice Wednesday after the injury surfaced during the win over the Chiefs.
- Cook returned to that game, but the club listed his setback as ankle and foot and is proceeding cautiously midweek.
- ESPN's Adam Schefter reported the issue involves both the foot and the ankle.
- If Cook is unavailable against the Dolphins, Ray Davis is expected to take most carries with Ty Johnson handling passing downs.
- Edge rusher Joey Bosa also missed Wednesday with a wrist injury, heightening depth questions after the Bills made no trades at the deadline.
