With 44 seconds left in the game, Foles dropped back to pass and attempted to avoid the Vikings’ rush, but Minnesota defensive end Ifeadi Odenigbo caught hold of the veteran quarterback and drove Foles backwards into the ground.
Bears coach Matt Nagy, in his postgame availability, said Foles had suffered a hip or leg injury.
Foles stayed down on the field for over a minute until the cart came out and transported him to the locker room.
Foles, 31, finished the night 15-of-26 for 106 yards and one interception.
The Bears (5-5) are on a bye week and next play at Green Bay on Nov. 29.
