Jaguars DE Aaron Kampman (knee surgeries) will not participate in the beginning of voluntary workouts Tuesday. Fellow defensive lineman Tyson Alualu will also be absent as he recovers from his "minor" microfracture knee operation. Kampman's absence wouldn't typically be a concern for a 32-year-old, 10-year veteran, but he's been limited to just 20 games by injury the past three seasons, and is coming off supposedly minor December knee surgery. He's undergone three known knee operations since December of 2009, including ACL reconstructions in each knee. Due $4.975 million, Kampman could be cut loose after the draft.
