Week 13 Outlook
49ers' RG Tom Compton suffered a concussion during a walk-through and will be out for Week 12.
This may have a negative effect on Raheem Mostert in his return from an ankle injury. The Rams have a stout D/ST and it's still not known if LT Trent Williams will be active. Fantasy managers who held on to Mostert might want to consider other options if available.
