Jaguars DE Aaron Kampman will miss the remainder of the season after tearing the ACL in his right knee.
The ninth-year veteran suffered the injury in Thursday's practice, and underwent an MRI on Thursday night, which revealed the tear.
Kampman was the Jags' most effective pass rusher, leading the team with four sacks. He suffered an ACL tear in his left knee while playing for the Packers last season.
The way we see it
The loss of Kampman is a huge blow for the Jaguars. The nine-year veteran, who turns 31 later this month, was the leader of the Jaguars' defense up front, both on and off the field, and Jacksonville will struggle to replace his presence.
The Jags' are unlikely to replace Kampman with the recently benched Derrick Harvey, meaning they will have to turn to rookie DEs Austen Lane and Larry Hart to pick up where Kampman left off.
