Arizona Cardinals: Running back Beanie Wells is back on the 53-man rosters after recovering from a toe injury. He's expected to play against St. Louis in Week 12. Wells, who had 228 yards rushing against the Rams in Week 12 last season, returns just as injured ribs are limiting running back LaRod Stephens-Howling. Quarterback Kevin Kolb remains limited by injury and is not expected to play Sunday. Ryan Lindley was already named the starter. Tight end Todd Heap was a full participant in practice for the first time since Week 2. Defensive end Calais Campbell, who missed the team's game at Atlanta with a calf injury, was limited in practice Wednesday.
St. Louis Rams: The Rams are getting center Scott Wells back from injured reserve following a foot injury. Wells upgrades depth and quality. His experience could help the Rams deal with the Cardinals' frequent blitzes. Steven Jackson (foot) and Danny Amendola (foot) did not practice Wednesday. Jackson is expected to play. Amendola's status could be more tenuous. He was reportedly wearing a walking boot. The team expects to be without linebacker Mario Haggan (elbow), possibly for the long term. He's a situational player. The team gave tight end Lance Kendricks rest Wednesday. He has a knee issue.
San Francisco 49ers: Alex Smith has not yet been cleared to play following the concussion he suffered in Week 10. Smith has been practicing, however, and could be available. Colin Kaepernick is expected to take the first-team reps and start against New Orleans. The 49ers are otherwise mostly healthy after having their bye two weeks ago.
Seattle Seahawks: Guard James Carpenter has been cleared to return from a concussion. He could start at left guard against Miami. Carpenter was limited Wednesday. Seattle, like San Francisco, appears mostly healthy following a recent bye. The team continues to list running back Marshawn Lynch (back) on its participation report. He practiced fully. Linebacker K.J. Wright is back at practice after missing time with a concussion. He's expected to start against the Dolphins.
