Kampman, who was out most of last season with a torn ACL, has missed the first month of the season because of side effects from the knee injury.
Del Rio jokingly said that the only way Kampman would play this week would be if "we have someone who slips on a banana peel between now and Sunday."
The Jaguars will be without several other key players on defense, as cornerback Derek Cox will miss his third-straight game of the season, this time with a groin injury. Running back and special teams stud Montell Owens is out with a knee injury.
Defensive tackle Tyson Alualu and left tackle Eugene Monroe are probable for this week's contest, while another special teams standout and receiver Kassim Osgood (hamstring) is doubtful. Joining Osgood on the 'doubtful' list is tight end Zach Miller (shoulder) and offensive lineman Jason Spitz (quadriceps.)
