After Sunday’s victory over the Chiefs, Cardinals coach Bruce Arians said that running back Andre Ellington would not play again this season after having sports hernia surgery.

The team made that official on Monday by placing Ellington on injured reserve. They also announced that they have signed safety Chris Clemons to fill the open roster spot.

Clemons hasn’t played at all during the regular season. He was with the Texans in training camp, but got released during final cuts this summer and hasn’t landed another job despite a few workouts and reports of interest around the league. He started all 32 games for the Dolphins the last two seasons and has spent all five of his NFL seasons in Miami, including three years with current Cardinals defensive coordinator and former Dolphins defensive backs coach Todd Bowles.

Clemons will give the Cardinals a bit more depth in the secondary with Tyrann Mathieu sidelined by a broken thumb.
