San Francisco 49ers receiver Mario Manningham aggravated a shoulder injury in his team's loss to the St. Louis Rams this weekend, and he's one of many banged up players in the NFC West.
Meanwhile, the Rams were without receiver Danny Amendola, who continues to recover from a foot injury that he suffered in the last meeting with the 49ers, a 24-24 tie.
The Arizona Cardinals are one of the teams in the NFC West being hit the hardest on the injury front. Ken Whisenhunt's team lost linebacker Paris Lenon for part of Sunday's game against the New York Jets with a shoulder injury, but he managed to return. The Cardinals were without leading receiver Andre Roberts (ankle) and defensive end Calais Campbell (calf) on Sunday as well, while starting quarterback Kevin Kolb is still on the mend because of a rib injury.
The Seattle Seahawks are another team with a few big injuries. Left guard James Carpenter tweaked a knee that underwent ACL surgery over a year ago and his status is now in question. Meanwhile, wide receiver Sidney Rice will undergo concussion tests as a precautionary measure after he was hit in the head on a game-winning catch in overtime that gave Seattle a victory against the Chicago Bears.
