Lions head coach Dan Campbell said on Monday that cornerback Terrion Arnold will be out for “[a long time](https://www.nbcsports.com/nfl/profootballtalk/rumor-mill/news/terrion-arnold-will-be-out-a-long-time-with-shoulder-injury)” because of a shoulder injury, but that he did not know if Arnold would miss the rest of the season.
It looks like there’s a good chance that will be the case. Tom Pelissero of NFL Media reports that Arnold [is likely to be out](https://x.com/TomPelissero/status/1975538363831632180) for the rest of the year, but that he is soliciting more opinions before such a determination is finalized.
Arnold has started all five games this season. He has 22 tackles and four passes defensed. The 2024 first-round pick had 60 tackles, 10 passes defensed, and a fumble recovery during his rookie season.
The Lions also have D.J. Reed on injured reserve for at least three more games and Khalil Dorsey is dealing with a wrist injury, so they will be short on corners against the Chiefs in Week 6 and beyond.
