49ers LT Trent Williams day-to-day with sprained ankle

It was a little surprising when 49ers left tackle Trent Williams showed up Wednesday as a non-participant in the team’s practice report. Head coach Kyle Shanahan indicated before the session that ankle and elbow injuries would be the cause of Williams’ absence, but Thursday the team specified a sprained ankle for the left tackle. He’s day-to-day.

Williams missed two games for the 49ers last season and played in Week 5 this year despite missing part of the fourth quarter of a Week 4 loss to the Seahawks because of a shoulder issue.

His absence early in the week doesn’t necessarily rule him out for Sunday, but it certainly isn’t a great sign.

Rookie left tackle Jaylon Moore would be next in line to replace Williams. Moore played 22 snaps in Williams’ stead in Week 4 and performed well enough to hold down the swing tackle spot. He also filled in there during the preseason when Williams wasn’t playing in games.
