Jackson (quad) did not participate in Wednesday's practice, ESPN's Vaughn McClure reports. Though previous reports suggested that the quad injury Jackson suffered in Week 16's game against the Saints isn't believed to be serious, it's worth noting that that the Falcons promoted running back Jerome Smith to their active roster on Wednesday, which could signal concern over Jackson's status for for Sunday's contest against the Panthers. In the event that he is limited or out this weekend, Devonta Freeman and Jacquizz Rodgers would be in line to see added touches in Week 17.
