Williams (ankle) is listed as questionable for Sunday's game against the Packers, Matt Barrows of The Athletic reports.
Williams has been held out of practice all week due to a lingering ankle issue, though it appears the 49ers will wait to announce his status for Sunday's game until approximately 90 minutes before the 4:25 p.m. ET kickoff. If Williams doesn't end up playing, Jaylon Moore would be the top candidate to start at left tackle.
