HENDERSON, Nev. — Las Vegas Raiders defensive end Malcolm Koonce is out for the season due to a knee injury suffered in practice three days before the team's season opener, a team source confirmed Friday night.
Koonce, coming off a career-best eight sacks and three forced fumbles in 2023 and entering a contract year, was placed on injured reserve Sept.
8. Chris Snowden started the team's first two games in Koonce's place opposite three-time Pro Bowl edge rusher Maxx Crosby. With second-year defensive end Tyree Wilson suffering a knee injury in the opener at the Los Angeles Chargers and missing Week 2 at the Baltimore Ravens, Las Vegas signed former first-round draft pick K'Lavon Chaisson to the practice squad.
Chaisson was elevated to the 53-man roster and played against the Ravens before being reverted to the practice squad, though he could be elevated again.
