Wallace was placed on the Ravens' IR list on Sept. 25 after he sustained a hamstring injury in Week 3 against the Colts. If he's able to suit up for Sunday's contest, he'll likely assume a role on special teams as he sits far down on the wide receiver depth chart.
Wallace has sat out the requisite four games after originally being placed on the injured reserve list prior to Week 4, and he was able to return to practice Wednesday. The Ravens' injury reports over the week will shed more light on whether he'll be able to play Sunday at Arizona.
