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.

Detroit Lions safety Morice Norris Jr. is in stable condition after suffering a serious injury during Friday night's preseason game against the Atlanta Falcons, the team said.
