Koonce was listed as a limited participant for Thursday's practice session due to a knee injury.
Koonce was able to participate fully during Wednesday's practice, but he now appears to be nursing a knee injury. His participation level during Friday's session will provide a better indication for his availability for Week 1 against the Chargers on Sunday. Koonce played in all 17 regular-season games for the Raiders in 2023, and he finished with 43 tackles (32 solo), including 8.0 sacks, and three forced fumbles. The 2021 third-round pick is slated to start on the Raiders' defensive line alongside Maxx Crosby, John Jenkins and Christian Wilkins.
