Koonce will undergo season-ending knee surgery next week, Tashan Reed of The Athletic reports.
Koonce sustained a knee injury during practice leading up to Week 1 against the Chargers. There was optimism that the 2021 third-round pick could return during the regular season, but following additional evaluations on his knee, it was determined that surgery is best for Koonce's long-term health, per Reed. Koonce entered the season with high hopes after breaking through in 2023, finishing with 43 tackles (32 solo), including 8.0 sacks, and three forced fumbles across 17 regular-season games. He will enter the 2025 offseason as an unrestricted free agent.
