CHARLOTTE, N.C. — Hollis Thomas has signed with the Carolina Panthers, another move made by a struggling team trying to fill their void at defensive tackle.

Rookie tackle Ra'Shon Harris was released on Thursday to make room for Thomas, who was let go by St. Louis a day earlier.

The 35-year-old Thomas was a reserve in three games for the Rams and made four tackles. He provides another option for winless Carolina, which has been unable to effectively replace Maake Kemoeatu, who was lost for the season in training camp with a torn Achilles' tendon.

The Panthers also lost backup Louis Leonard to a season-ending broken ankle in Week 2. Second-year pro Nick Hayden started in Monday's loss to Dallas.

Harris was claimed off waivers last month after being cut by Pittsburgh.
