Bennett, who has sat out of practice all week with a shoulder injury, is listed as doubtful to suit up against Detroit.
Linebacker Ahmad Brooks (back) and defensive tackle Quinton Dial (chest) are also doubtful after failing to log a practice all week.
There is some better news though.
Tackle David Bakhtiari (hamstring), safety Morgan Burnett (hamstring), running back Ty Montgomery (ribs/wrist) and linebacker Nick Perry (hand) are all set to play. All four practiced fully each week and don’t carry an injury designation.
