Williams (head) did not play in Friday night's 28-25 preseason win over the Vikings.
Williams was examined for a concussion during last Friday's exhibition outing, so it's not surprising to see him sit out this week's preseason finale. The veteran's status will have to be monitored in advance of Week 1's matchup versus the Browns, but once cleared, Williams profiles as a rugged backup to versatile starter Clyde Edwards-Helaire.
