Before Baltimore Ravens QB Lamar Jackson (knee) returns to the practice field for the first time since sustaining a posterior cruciate ligament sprain in Week 13, he will need to go through football-related movements such as stopping, starting, cutting and reacting. Jackson has experienced no difficulty running on a treadmill or moving straight ahead. Sources believe that he should be able to resume playing once he is cleared to practice.
