Overview
- San Francisco placed first-round defensive lineman Mykel Williams on injured reserve after tests confirmed a torn ACL suffered late in the Week 9 win over the Giants.
- The team activated offensive lineman Ben Bartch from injured reserve to fill the roster spot opened by Williams' move to IR.
- Defensive linemen Clelin Ferrell and Sebastian Valdez were elevated from the practice squad for the Week 10 matchup against the Rams.
- Ferrell is available for Sunday after recording a sack in last week's victory at MetLife Stadium.
- Under NFL rules, Ferrell's third temporary elevation means the 49ers must sign him to the 53-man roster for any future game-day availability.
