The Rams have been without starting center Brian Allen for the last three weeks and now backup Coleman Shelton, moved over from right guard to replace Allen, appears to be out of the game. We think. Shelton left in the 1st quarter with an ankle injury, went to the locker room, returned without missing any snaps, and then went back into the locker room. Third-string Jeremiah Kolone is next up. The Rams are already without LG David Edwards (concussion) and only have Bobby Evans, recently-signed Oday Aboushi, and Chandler Brewer, called up from practice squad on Monday. as OL depth.
