Coach Sean McVay suggested Friday (ankle) that Williams won't be activated for Sunday's game against the 49ers, Stu Jackson of the Rams' official site reports.
Williams was designated Wednesday to return from injured reserve, opening a 21-day window for the Rams to activate him or put him back on IR for the rest of the season. They may bring him back as soon as Week 9 at Tampa Bay, as the current backfield situation is less than optimal with Cam Akers still sidelined for non-injury reasons and a candidate to be traded. Darrell Henderson (illness) and Malcolm Brown figure to lead the way Sunday against the Niners.
