Dixon's teammate Karlos Williams suffered a concussion during Sunday's loss to the Giants, NFL.com's Ian Rapoport reports.

EDGE Analysis

Williams could still get through the league's concussion protocol in time for Sunday's game in Tennessee, plus there's a long shot that LeSean McCoy could rally from his hamstring injury. But we'll note that Dixon is the clear next back in the pecking order behind those two, so there's a chance he could be more than just a short-yardage guy this week.
