Not entirely surprising, as both Kevin Kolb and Sam Bradford's injuries have been well publicized for the last week, but it's looking more and more like both the Rams and Cardinals will go into Sunday's game starting their backup quarterbacks. Bradford has been listed as questionable and Kolb as doubtful, but from most accounts it's looking likely that neither will play (Rams coach Steve Spagnolo noting that Bradford is "questionable as can be"). That leaves John Skelton picking up the slack for the Cardinals and A.J. Feeley doing the same for St. Louis.
Apart from that, each team is experiencing, to an extent, the mid-season injury bug. Arizona will be without Rob Housler, Joey Porter, Kerry Rhodes, Anthony Sherman, and as stated above, probably Kevin Kolb. In addition to that, they've got five players listed as questionable - Todd Heap and Beanie Wells among them.
The Rams are faring a little better, but will be without the services of Danario Alexander, Jerious Norwood, Darell Scott, and Jason Smith.
Below are the official injury reports for Friday for each team.
