The Ravens ruled out Pro Bowl kick returner Jacoby Jones for the second consecutive week due to a sprained medial collateral ligament in his right knee.
Jones is expected to be out four to six weeks, according to sources.
Five other players didn't practice Wednesday, including Pro Bowl running back Ray Rice (left hip flexor strain), inside linebacker Arthur Brown (left strained pectoral), cornerback Chykie Brown (right knee), defensive end Chris Canty (strained groin), center Ryan Jensen (foot surgery).
