Williams (thigh) is listed as questionable for Sunday's game against the Browns, Tim Twentyman of the Lions' official site reports.
Williams has been sidelined for Detroit's last two games, but he appears to have a better shot at playing this week compared to the previous two contests after practicing on a limited basis Wednesday through Friday. If the Lions determine that Williams will need another week off, Godwin Igwebuike would be in line to serve as starter D'Andre Swift's clear top backup. The other running back on the Lions' 53-man roster, Jermar Jefferson (knee/ankle), has already been ruled out for the game.
