Williams (ribs/illness) will participate in Wednesday's practice, BJ Kissel of the Chiefs' official site reports.
It won't be known until after the session concludes whether Williams was a limited or full participant, but the fact that he's opening Week 16 on the practice field can be viewed as a positive. The 27-year-old looked to have just about moved past his rib injury in Week 15 after practicing Wednesday and Thursday, but an illness kept him sidelined Friday and ultimately caused him to miss a third consecutive game. Assuming Williams has recovered from both the rib injury and illness ahead of Sunday's matchup with the Bears, he could head a backfield committee that also includes LeSean McCoy, Darwin Thompson and Spencer Ware.
