As has been the case for most of the season, the Bears could be shorthanded at key positions due to injuries Sunday when they visit the Minnesota Vikings.
Nickel back Bryce Callahan (quad) is listed as doubtful, while receiver Alshon Jeffery (calf), outside linebacker Pernell McPhee (knee), cornerback Tracy Porter (ankle) and tight end Zach Miller (rib) are among six Bears players who are questionable. The others are defensive lineman Will Sutton (knee) and cornerback Sherrick McManis (concussion).
