NFC West injury situations that matter

Arizona: Quarterback Kevin Kolb took all the first-team reps in practice Wednesday for the first time since suffering toe/foot injuries against Baltimore one month ago. That puts Kolb on course to start against Dallas. Running back Beanie Wells was limited, but his 27-carry, 228-yard performance against Arizona suggests his knee injury is no longer holding him back much. And with fullback Anthony Sherman also healthy, the Cardinals' offensive backfield finally appears whole. That gives the team a chance to more accurately evaluate its offense over the final five games of the season. Hamstring trouble continues to limit tight end Todd Heap, but rookie Rob Housler practicing fully. Tight end Jeff King has become a preferred outlet against pressure for Arizona quarterbacks.

St. Louis: The team limited quarterback Sam Bradford in practice as a precaution after Bradford aggravated his ankle injury against Arizona. Bradford remains the expected starter against San Francisco, but with both starting tackles out for the season, his well-being is a concern Sunday. Adam Goldberg is expected to make his second consecutive start at left tackle. He struggled against Arizona's Sam Acho last week. The challenge grows against the 49ers' Justin Smith and Aldon Smith. On defense, Rams safety Darian Stewart remains sidelined by a concussion. He has been a willing hitter and an occasional playmaker. The Rams would miss him.

San Francisco: The 49ers are expected to have fullback Bruce Miller back from a concussion this week. The team missed Miller against Baltimore. Getting Miller back could help the running game and the offense overall. However, the 49ers could remain without starting right guard Adam Snyder, who is recovering from a hamstring injury. Snyder has been a stabilizing force on the right side of the line. The 49ers might be wise to rest him, in my view. The same goes for receiver Braylon Edwards, whose play has suffered from injuries to his knee and shoulder.

Seattle: Sidney Rice's placement on injured reserve with a concussion hurts the offense. Mike Williams, Golden Tate, Deon Butler and Ben Obomanu figure to get more playing time. The team needs to find out more about Tate and Butler in particular. That should happen over the final five games. Quarterback Tarvaris Jackson has practiced this week despite the pectoral injury that has affected his play in recent weeks. Defensive tackle Alan Branch has returned to practice this week. The Seahawks' run defense missed him against Washington.
