Collier has been out since Week 2 with a knee injury.

The Arizona Cardinals could have some defensive line reinforcements soon. On Wednesday, they designated defensive lineman L.J. Collier to return from injured reserve. That move opened a 21-day window allowing him to participate in practice.

Getting designated to return means that he must be activated during or at the conclusion of the 21-day window or revert to IR for the rest of the season.

Collier injured his knee in Week 2 against the Carolina Panthers. He has one tackle in two games this season.

Last season, he had a career season. In 17 games with 15 starts, he had 29 tackles, 3.5 sacks, four tackles for loss and six quarterback hits. They were career-high marks in games, tackles and sacks, and he tied his career-high in tackles for loss.

In his third season with the Cardinals, he has been unlucky with injuries. He played in just one game in 2023, losing the rest of his season to a torn biceps. He played in all 17 games last season and missed 10 games after two games this year.
