The Arizona Cardinals had a significant absence as they returned to work this week looking to revive what began as a promising season but has descended into the misery of a five-game losing streak.
Defensive end Calais Campbell sat out Wednesday's practice because of a calf injury and his status for Sunday's game at Atlanta is uncertain.
Coach Ken Whisenhunt says his long evaluation of the team over the bye week has led to some strategy adjustments, but he said he couldn't discuss details. Last week, the coach announced that rookie Jake Potter, a seventh-round draft choice from Boise State, would replace D'Anthony Batiste at left tackle on the beleaguered offensive line. That leaves Arizona with rookies at both tackle positions. Fourth-round pick Bobby Massie starts on the right side.
