Lake Forest, IL -- (Sports Network) - Chicago Bears defensive tackle Tommie Harris is listed as doubtful for Sunday's contest at Cincinnati.

Harris, who has nine tackles in five games this season, missed the last three days of practice with soreness in the knee he injured early last season.

The 6-foot-3 312-pounder had three total tackles -- one for a loss -- in the Bears' setback at Atlanta last Sunday. The injury is not expected to be a long termed concern according to head coach Lovie Smith.

Also listed as doubtful is running back Adrian Peterson (knee).
