The biggest concern now is not even the possibility of being without Jared Veldheer at left tackle and Adrian Peterson at running back
No, the biggest worry now is that Patrick Peterson was downgraded on Thursday from limited to did not participate.
The Cardinals could be without Veldheer, Peterson and Peterson on Sunday, which would be a big problem.
Josh Mauro, another starter is also listed on the did not participate list, but his void would seem to be the easiest to fill.
Upgraded on Thursday were John Brown, to limited, and Deone Bucannon to full, which could be good for the Cardinals in both instances.
The Cardinals come into their matchup with the Titans hobbled in two of the most important spots, on top of already being down to their third quarterback.
Things can always get worse.
