Vaughn, Waddle ruled out for Lions
The Lions have already lost cornerbacks Bill Bentley and Nevin Lawson to season-ending injuries, and safety James Ihedigbo hasn't played yet - he's doubtful for Sunday with a neck problem. Safety Don Carey, who hasn't played yet because of a hamstring injury, is probable.
Tackle LaAdrian Waddle has been ruled out with a calf injury.
