What happened: Campbell suffered the injury in Detroit's Week 8 win over Minnesota. The Lions placed him on injured reserve Nov. 7.
Why it matters: Detroit is playing without its 2023 first-round linebacker. Campbell was the 18th overall pick in that draft.
By the numbers: Campbell made 57 tackles in seven games in 2026, an average of 8.1 per game.
What to watch: A change to Campbell's injured reserve status would be the next roster development.
