The Packers have ruled LB De'Vondre Campbell (knee) out for Sunday's game against the Lions. DC Joe Barry said earlier in the week that rookie LB Quay Walker would take over play-calling duties if Campbell couldn't go. That should mean full playing time for Walker, who has moved up our Week 9 IDP rankings. EDGE Preston Smith (shoulder, neck) is questionable for the game after being limited in practice all week.
