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 preseason matchup Friday night between the Detroit Lions and the Atlanta Falcons has been suspended after Detroit safety Morice Norris Jr. suffered a serious injury.
