Zac Stacy, Trumaine Johnson, Chris Williams cleared through concussion protocol

The San Francisco 49ers will face a relatively healthy St. Louis Rams squad this Sunday. The team was able to clear running back Zac Stacy, cornerback Trumaine Johnson and guard Chris Williams after they suffered concussions last week against the Chicago Bears. All three are listed as probable for Sunday.

Stacy's availability is a significant boost for the Rams. Backup Benny Cunningham has looked solid when he gets on the field, but having a healthy Stacy gives the Rams that much more depth. The Rams will be looking to establish the ground game in order to take pressure off Kellen Clemens and the passing game.

The return of Williams, and the potential return of Dahl bodes well for a Rams offensive line that has been fairly solid this season. Football Outsiders ranks them No. 4 in adjusted line yards and No. 14 in adjusted sack rate. The 49ers are coming off a dominant performance against the Washington offensive line, and will look to build on that against the Rams offensive line.

Rams injury report

Questionable: S T.J. McDonald (shin), CB Brandon McGee (foot), G Harvey Dahl (knee)

Probable: CB Trumaine Johnson (concussion), RB Zac Stacy (concussion), G Chris Williams (concussion), DE Eugene Sims (foot)
