The Ravens were without wide receiver Torrey Smith (knee), running back Lorenzo Taliaferro (foot), and tight end Crockett Gilmore (back) for Wednesday's practice.
Smith, who was held out of Week 14's game aganist the Dolphins, has been dealing with knee swelling over the past two weeks.
Taliaferro saw his first carries in three weeks against Miami when he had seven carries for 35 yards and one catch for 20.
The Ravens face the Jaguars in Week 15.
