NFC West: Injury situations that matter

Arizona: The Cardinals listed 16 players on their injury report for the team's Thursday night game in St. Louis. Cornerback Michael Adams (hamstring), tight end Jim Dray (knee), outside linebacker Quentin Groves (hamstring), tight end Todd Heap (knee), running back LaRod Stephens-Howling (hip), defensive end Darnell Dockett (hamstring), linebacker Paris Lenon (knee), quarterback John Skelton (ankle) and nose tackle Dan Williams (foot) were questionable. Seven others were probable. None was doubtful. Running back Beanie Wells remains out until Nov. 25. Having Stephens-Howling available would give the Cardinals' needed options on offense, particularly in no-huddle situations. Dockett missed the most recent game and he was limited Wednesday. Skelton has practiced fully the past two days, but Kevin Kolb remains the starter.

St. Louis: The Rams listed running back Steven Jackson (groin) and left tackle Wayne Hunter (knee) as questionable. Both practiced on a limited basis over the past two days. Both are expected to play against the Cardinals. Jackson was able to run hard against Seattle. Starting left tackle Rodger Saffold (knee) and backup defensive end Eugene Sims (head) will miss the game. The three players listed as probable practiced fully Wednesday. That list included receivers Danny Amendola (ankle) and Brandon Gibson (knee), and backup defensive end William Hayes (knee).

San Francisco: Running back Brandon Jacobs (knee) could be available for the first time this season. The 49ers have good depth at the position already, however, and some of their other running backs contribute more on special teams. If Jacobs doesn't play against Buffalo, I'd expect him to be active against his former team, the New York Giants, a week later. The 49ers are relatively healthy overall. Nose tackle Isaac Sopoaga (knee) missed the game against the New York Jets and was limited in practice. He could be available this week, but the 49ers probably will not need him much against Buffalo. San Francisco will likely use its sub packages heavily against the Bills' offense. Linebacker NaVorro Bowman (shoulder) and cornerback Carlos Rogers (ankle) were also limited in practice.

Seattle: The Seahawks have used eight starters on their offensive line, tied with Jacksonville for most in the NFL through Week 4. One of the eight, guard/center John Moffitt, will not be available against Carolina. Seattle listed him as out with a knee injury. James Carpenter's return from 2011 knee surgery last week gives the team welcome flexibility. Carpenter started at left guard and survived an injury scare. Paul McQuistan will start at right guard for a second consecutive week. Cornerback Marcus Trufant (back) and defensive end Jaye Howard (foot) missed practice Wednesday. The team gave running back Marshawn Lynch the day off. Trufant's role as the nickel corner gets him on the field for roughly 40 percent of the snaps, depending on the opponent. Carolina's opponents have played with at least one additional defensive back about 60 percent of the time when the score was within eight points and 80 percent of the time otherwise, according to ESPN Stats & Information.
