The Bears medical staff carted off wide receiver Johnny Knox in the first quarter of Sunday's game against the Seahawks because of what appeared to be a back injury. Knox took a vicious shot from Seahawks defensive end Anthony Hargrove while scrambling for a fumble at the end of a 17-yard catch over the middle. He was down for approximately 10 minutes as he was immobilized by the medical staff and later carted off the field on a stretcher. While lying on the stretcher, Knox appeared to be responsive and moving his hands.
