Detroit Lions safety Morice Norris, who was taken off the field in an ambulance late in a preseason game last week, is in concussion protocol and doing well, coach Dan Campbell said Monday.

Detroit Lions defensive back Morice Norris was carted off the field with what appeared to be a neck injury early in the fourth quarter Friday.

The positive updates continue, with the Associated Press reporting Norris was back at the team facility Sunday, after returning home on Saturday.
