With 13 players listed on their injury report, the Bears could be shorthanded again Sunday when they visit the Detroit Lions at Ford Field.
Linebacker Shea McClellin (knee), defensive lineman Ego Ferguson (ankle), safety Antrel Rolle (ankle) and cornerback Terrance Mitchell (hamstring) all are doubtful after being missing practice Friday, meaning there's only a 25 percent chance they'll play.
Eight players are questionable (and have a 50/50 chance of playing): Receivers Alshon Jeffery (hamstring), Eddie Royal (ankle) and Joshua Bellamy (groin); tight end Martellus Bennett (quad); left tackle Jermon Bushrod (shoulder); guard Patrick Omameh (ankle); outside linebacker Pernell McPhee (shoulder); and defensive lineman Jeremiah Ratliff (ankle).
