NFC West: Injury situations that matter

Arizona Cardinals: The Cardinals placed quarterback Kevin Kolb on injured reserve, where he joins left tackle Levi Brown, center Lyle Sendlein, backup center Rich Ohrnberger, outside linebacker O'Brien Schofield, running back Ryan Williams and others. Rookie Ryan Lindley will start at quarterback against Detroit. Receiver Early Doucet (concussion), defensive lineman Ronald Talley (ankle) and nose tackle Dan Williams (hamstring) did not practice. Defensive end Calais Campbell (calf), defensive tackle Nick Eason (ankle), tight end Rob Housler (knee), safety Kerry Rhodes (abdomen), receiver Andre Roberts (ankle) and cornerback Greg Toler (hamstring) were limited. Coaches and players have long said training rooms tend to clear out when a team is winning because players are so eager to get onto the field. Arizona's nine-game losing streak robs the Cardinals of that additional incentive.

St. Louis Rams: The Rams held out cornerback Cortland Finnegan (ankle), safety Craig Dahl (head), running back Steven Jackson (foot), middle linebacker James Laurinaitis (back), tight end Mike McNeill (thigh) and center Scott Wells (knee). Linebacker Mario Haggan (elbow) was a full participant. The one player limited in practice, receiver Danny Amendola, is the most volatile variable. Coach Jeff Fisher indicated Amendola needs to be near full strength to function at a high level. That is presumably because Amendola depends on his quickness and ability to change directions, attributes compromised by a foot injury. The Rams have won their past two games without Amendola. Rookie receiver Chris Givens has filled some of the void. But having Amendola in the lineup would certainly improve the Rams' chances.

San Francisco 49ers: The 49ers listed linebacker Tavares Gooden (ribs), receiver Mario Manningham (shoulder), fullback Bruce Miller (shoulder) and linebacker Aldon Smith (shoulder) as limited. Kicker David Akers (pelvis), linebacker Navorro Bowman (shoulder), cornerback Tarell Brown (shoulder), cornerback Chris Culliver (knee), running back Frank Gore (wrist), cornerback Carlos Rogers (knee), defensive tackle Will Tukuafu (wrist) and linebacker Patrick Willis (shoulder) are listed as full participants. Manningham's status is most compelling. While most or all the other injured players are expected to play against New England, Manningham missed the Week 13 game at Miami, so his status is in a bit more question. Randy Moss figures to play extensively regardless, but if Manningham misses the game, the 49ers could feature Moss a bit more against his former team.

Seattle Seahawks: Seattle held out receiver Sidney Rice (foot), cornerback Marcus Trufant (hamstring), safety Kam Chancellor (groin) and defensive end Red Bryant (foot) missed practice Wednesday. The team continues to list running back Marshawn Lynch (back) as limited despite every expectation he'll be able to play. Cornerback Walter Thurmond (hamstring) was a surprise addition to the injured list Wednesday. He's had injury problems in the past. Durability is a concern. Depth at corner isn't as strong with Brandon Browner serving a suspension and Trufant sidelined recently. Seattle is no longer listing linebacker Leroy Hill (ankle). Malcolm Smith could wind up keeping the job.
