The Browns placed linebacker Anthony Walker Jr. on injured reserve Friday, the team announced.
Walker is out for the season with a torn quadriceps muscle that requires surgery.
Walker, voted a team captain this season, started all three games. He totaled seven tackles, four tackles for loss and two passes defensed.
Walker initially signed a one-year deal with the Browns in March 2021 and played nine games for the team last season. He re-signed with Cleveland on a one-year deal in March.
The Colts selected Walker in the fifth round of the 2017 draft, and he spent his first four seasons in Indianapolis.
