Williams ran four times for 16 yards -- including a one-yard touchdown -- and caught his only target for 19 yards during Sunday's 27-20 loss to the Cowboys.
With J.D. McKissic (concussion) expected to miss his second consecutive game, Washington signed Williams off the Giants' practice squad ahead of Week 14. The 27-year-old running back split time with Jaret Patterson in reserve of Antonio Gibson, and while the two backups shared similar yardage totals, Williams touchdown separated him from the pack. However, even if McKissic is sidelined for a third straight game, neither backup likely garners much fantasy potential heading into Sunday's showdown with the Eagles.
