Cardinals CB Patrick Peterson left Sunday's loss to the Buccaneers with a calf injury. It's not yet clear how serious the injury might be. We'll keep an eye on his situation throughout this week. Arizona slot CB Tramaine Brock missed Week 10 with a hamstring injury that kept him out of practice all week. That could leave the Cardinals without 2 of their top 3 cover guys for the Week 11 visit to San Francisco.
The Cardinals watched 2 DBs leave Sunday's win over the Eagles with concussions. CB Patrick Peterson suffered his injury in a 1st-half collision with Jeremy Maclin. Jefferson played 75 of the 94 snaps and had his injury revealed Monday. Both will need to pass through the league protocol before returning to action. Fortunately, neither is much of an IDP factor. Jefferson's recent playing time hasn't proved consistent enough for fantasy owners to trust him. Losing him for Sunday's trip to Dallas wouldn't affect the outlook for the team D. Peterson has failed to live up to his reputation in coverage this year, but missing him would still only make Arizona a more positive passing matchup for Tony Romo and the Dallas WRs in Week 9.
