What happened: Detroit Lions linebacker Jack Campbell remained in a local hospital following a neck injury suffered during Sunday's game. Campbell exited the contest before Detroit closed out a 19-15 victory over the Minnesota Vikings.

Why it matters: Campbell anchors the interior of Detroit's defense and serves as a primary defensive leader. Any extended absence for the linebacker tests Detroit's depth as the club moves through its regular-season schedule.

What to watch: The Lions await official medical updates following Campbell's hospital stay. Detroit will update his status when the team releases its next injury report.
