Detroit Lions cornerback Terrion Arnold was placed on injured reserve Monday, meaning he’ll miss at least four games.

But according to an NFL Network report, he is set to have season-ending shoulder surgery this week.

This would bring Arnold’s injury-plagued second season to an end. He originally sustained a shoulder injury during a Week 5 game against the Cincinnati Bengals, with Lions coach Dan Campbell saying he would be “out for a long time.”

However, Arnold returned in Week 9 versus the Minnesota Vikings, recording his first career interception before sustaining the concussion the following week against the Washington Commanders.

Arnold returned from a two-week absence on Thanksgiving against the Green Bay Packers. He played in just 18 plays and is now reportedly done for the season.

Arnold, 22, was Detroit’s first-round pick in 2024. After appearing in 16 games (15 starts) as a rookie, he’s appeared in eight games this season, recording 31 tackles, eight pass breakups and one interception.

The Lions (7-5) currently sit in third place in the NFC North, two games behind first-place Chicago. They’re the first NFC team out of the playoffs if they began today, 1 1/2 games behind San Francisco (9-4) entering Thursday’s home game vs. Dallas.
