Williams (knee) is active for Sunday's game against the Bengals, Aric DiLalla of the team's official site reports.
The standout rookie running back was described Saturday as likely to play, and that prognosis has proven to be correct. Backfield mate Melvin Gordon (hip/thumb) is also active Sunday, leaving the duo to likely operate in their usual highly effective timeshare against a Bengals defense allowing an NFL-low 81.3 rushing yards per game on the road.
