This seemed like a better idea than just individual fanshots. There shouldn't be any surprises on the inactive updates, but I know that you want to know about Jackson and Attogwe status for this game well here you go.
Rams inactives: TE Hoomanawanui, TE Bajema, DT Ryan, DT Scott, WR Robinson, S Stewart, LB Chamberlain and T Foster.
Butler and Dahl will start at safety. Atogwe available for depth or possibly situationally.
I got those from the Rams offical twitter page
Rams plan to keep running back Steven Jackson active, but they are unsure how much he'll be able to play.
