The Cardinals enter Week 12 with numerous injuries to key players and are unsure of the statuses for two of their starters. Defensive end Calais Campbell has battled a calf injury throughout the week and was a limited participant in all of the team's practices, making him questionable for Sunday. Most expect him to play, although head coach Ken Whisenhunt is unsure of just how much of an impact he'll be able to make.

"He's doing well. We'll see," Whisenhunt said of Campbell. "We'll work him out on Sunday like we normally do and see how we feel about that."

Beanie Wells has been activated from the injured reserve and was a full participant in practices all week. He has missed most of the season with a toe ailment.

"I think Beanie will be ready to go," Whisenhunt said. "We'll see. You never know what to expect since it's his first game in quite a while. Whatever we get out of him, if we can get something out of him, that will be good. We can certainly use some help there."

The Cardinals are set to kickoff with the St. Louis Rams at 2:25 p.m. MT on Sunday.
