Jaguars DE Aaron Kampman (knee) has a chance to return for Sunday's game against the Bengals. In each of the past two weeks, Kampman has been ruled out before the week even got going. On Monday, coach Jack Del Rio left the door open. Kampman has missed the last 12 games dating back to last season after tearing his ACL in a practice drill. The Jags have just six sacks through four games this season.
