What happened: Per Mike Garafolo, Detroit returner Tom Kennedy suffered a significant MCL injury. Surgery is expected, ending his season. Further testing revealed the full damage after Dan Campbell had hoped for a shorter absence.

Why it matters: Losing Kennedy forces Detroit to reshuffle its return rotation. Depth in the return game now becomes an immediate roster decision with the season underway.

What to watch: Detroit must identify a replacement returner and finalize the surgical plan.
