49ers' Trent Williams: Sidelined for Week 15

Williams (ankle) has been ruled out ahead of Thursday night's matchup against the Rams, Eric Branch of the San Francisco Chronicle reports.

Williams is now in line to miss his fourth consecutive game in Thursday night's divisional matchup due to an ankle injury sustained in November. Jaylon Moore is projected to continue serving as San Francisco's top left tackle until Williams recovers from the issue.
