Williams (knee) was a limited participant in practice Wednesday, Aric DiLalla of the Broncos' official site reports.
Fellow running back Melvin Gordon (thumb/hip) was also limited. There's little reason to believe either running back will sit out Sunday against the Chargers, though it will be worth checking back on both players' statuses as the week progresses. Williams and Gordon normally split carries, but if either were to sit, the other would become an even more enticing fantasy option Week 17 against a dreadful Chargers run defense that just got carved up for 149 yards and two touchdowns by Houston's Rex Burkhead.
