NFC West: Injury situations that matter

Arizona: Beanie Wells' turf-toe injury will sideline him until at least Nov. 25, putting pressure on second-year pro Ryan Williams to remain healthy. The team re-signed Alfonso Smith for depth, but Williams, LaRod Stephens-Howling and William Powell are ahead of him. Powell looked good while carrying 42 times for 249 yards (5.9-yard average) and three touchdowns during the preseason. Quarterback John Skelton practiced on his injured ankle, an indication he'll be available against Miami. Kevin Kolb presumably remains the starter. Defensive end Darnell Dockett (hamstring), tight end Todd Heap (knee), fullback Anthony Sherman (hamstring) and Stephens-Howling (groin). Dockett's injury will be one to watch. He's been playing at a high level. Heap appeared close to playing last week. Safety Adrian Wilson (groin) was among those limited in practice after sitting out last week.

St. Louis: Defensive tackle Michael Brockers returned to practice after missing the first three games with a high-ankle sprain. That's a good sign for the Rams as they prepare for Seattle's Marshawn Lynch. Brockers was limited in practice. Steven Jackson (groin) did not practice. The team remains without center Scott Wells and left tackle Rodger Saffold. A knee injury continues to limit Wayne Hunter, Saffold's replacement. Saffold could miss a few more weeks. Overall, though, the Rams are healthier than they were last season. One question is whether Jackson's groin injury will linger. He faces a Seattle run defense that has allowed 2.9 yards per carry on rushes excluding quarterback scrambles.

San Francisco: Linebacker Patrick Willis practiced despite the ankle injury he suffered against Minnesota. That's a welcome indication for Willis and the 49ers. Nose tackle Isaac Sopoaga (knee) missed practice. His status affects the 49ers' base defense heading into a Week 4 game against the New York Jets. The Jets have faced base or short-yardage defenses more than 60 percent of the time this season, according to ESPN Stats & Information. The 49ers continue to ease running back Brandon Jacobs (knee) and returner Ted Ginn Jr. (ankle) without any pressure to rush them. Both were limited participants. That marked progress for Jacobs, who was injured Aug. 18.

Seattle: Left tackle Russell Okung appeared to make it through the Green Bay game without suffering an injury setback to his knee. Former starting right tackle James Carpenter could be available for the first time this season. He projects at left guard, but it's not clear how much he'll play, or how soon. Seattle has not been afraid to rotate players at the other guard spot. Carpenter, a first-round pick in 2011, has been rehabbing from the knee surgery he underwent last season. Receiver Doug Baldwin (shoulder) was a last-minute scratch from the lineup against the Packers. He could return this week. Baldwin and cornerback Byron Maxwell (hamstring) practiced fully. Right tackle Breno Giacomini (pectoral), guard John Moffitt (knee) and defensive lineman Greg Scruggs (wrist) did not practice.
