What happened: Medical personnel attended to Jack Campbell on the turf after the Detroit Lions linebacker went down with a neck injury. Detroit players gathered on the field as staff assisted Campbell off the playing surface. The Lions protected their late advantage to finalize a 19-15 victory over the Minnesota Vikings.

Why it matters: Campbell serves as a centerpiece of Detroit's defense after he signed a long-term contract extension with the Lions. Any prolonged absence would place heavier responsibility on the defensive unit as Detroit continues its regular season campaign.

What to watch: The Lions will evaluate Campbell before providing an official update on his status. Detroit resumes preparations later this week for its next scheduled contest.
