TEMPE, Ariz. (AP) — 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 promised a detailed evaluation of his personnel during the bye week and was vague about the outcome.
"There are a couple of things we are going to do," he said, "but obviously from a strategy standpoint I don't think it behooves me to say anything about it. That will all play itself out."
The only personnel change Whisenhunt has confirmed is inserting rookie Jake Potter, a seventh-round draft choice from Boise State, to 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.
Quarterback John Skelton said he had full confidence in Potter.
"I think he'll do fine," Skelton said. "I could see it in Green Bay. He had the jitters a little bit, but the first play we asked him to block Clay Matthews. He did a great job and we got the ball down field to Andre (Roberts), and I think he'll only do better from here on out."
Skelton said he saw plenty of room for improvement as he examined his play, and the rest of the team's.
"People call the 4-0 start a fluke," he said, "and rightfully so, because we've lost the last five."
Skelton hinted that different players were taking more reps in practice this week.
"A lot of it is more subtle things," he said, "giving guys more reps than they've been getting in the past. But I think major overhaul changes, I haven't seen any of that. I think this week will tell us a lot about those types of moves."
Skelton returned as quarterback when Kevin Kolb went down with rib cartilage damage late in the overtime loss to Buffalo three games ago. With the running game virtually nil, Skelton has completed 80 of 134 passes for 858 yards and two touchdowns, with three interceptions, in consecutive losses to San Francisco, Minnesota and Green Bay.
"I looked back at some of the film from these last few games," he said, "I think across the board we've got to play better. Obviously, our record speaks to that."
Skelton cited "ball security" as his biggest needs for improvement.
