Williams (ankle), whom coach Sean McVay said Wednesday won't play Sunday against the Steelers, didn't practice Wednesday.
Williams is expected to miss multiple weeks due to a sprained ankle that he suffered this past Sunday against the Cardinals, so his lack of practice activity shortly after the injury doesn't come as a surprise. However, he was spotted with a cast on his left ankle and also needed a scooter to get around during Wednesday's session, per Adam Grosbard of The Orange County Register. With Ronnie Rivers' (knee) landing on injured reserve Wednesday, the Rams now are down their top two running backs for at least one game, leaving rookie sixth-rounder Zach Evans as the team's likely No. 1 back heading into the Week 7 matchup with Pittsburgh. Behind Evans, the Rams have Royce Freeman and Myles Gaskin on the active roster and Darrell Henderson on the practice squad.
