LAKE FOREST, Ill. — Derek Anderson, it's your turn. For how long remains to be determined.
The Cardinals' quarterback situation is up in the air after coach Ken Whisenhunt decided to shake up a struggling offense and start Anderson at quarterback over Matt Leinart in the third preseason game, tonight at Chicago.
"I realize we're not game planning," Whisenhunt said. "We're not doing a lot, so you're going to have some of those situations more so than we'd like to have, but still that would be something we'd look to improve on this week."
It's not clear if the move, announced Thursday, is permanent.
Leinart defended himself in an interview with the Arizona Republic.
"I've done everything to this point that they've asked me to and more," he said. "I've worked hard and been a leader. I'm trying to be that guy in this new role. I have high expectations for myself."
He said his performances have been "efficient."
But Leinart, penciled in as the starter after Kurt Warner retired, has yet to lead Arizona's offense to a score this preseason. He couldn't even get a first down in the three series he played against Tennessee in a 24-10 loss Monday.
That's right — three-and-out on all three series. The Heisman Trophy winner was 4-of-6 for 28 yards and is 10-of-13 for 77 yards in two preseason games, his longest completion a 16-yarder.
"I don't know how you judge performance when you have 13 pass attempts to the other guy's 40," Leinart told the Republic.
Said Anderson, the former Browns quarterback who has completed 24 of 41 passes for 193 yards with a touchdown and two interceptions: "I think I've made big strides since the spring."
CHIEFS: Running back Jamaal Charles limped away near the end of the first half of Friday night's preseason game after being forced out of bounds by Philadelphia rookie Nate Allen, a former USF star. Charles, who rushed for 1,120 yards last season, seemed to be holding his right arm, but it was not clear where he was hurt.
COLTS: The AP reported that linebacker Gary Brackett is not expected to miss significant time after X-rays on his injured right hand showed no major damage. Brackett was injured Thursday at Green Bay when he appeared to hit his hand on the helmet of teammate Philip Wheeler. … A day after Peyton Manning drew two penalties for illegal snaps in a loss at Green Bay, coach Jim Caldwell pleaded with league officials to re-evaluate a change that forces players to wait for the umpire to get into his new position before a ball can be put in play.
EAGLES: Receiver DeSean Jackson left Friday's game against the Chiefs after one play. Jackson left after taking a hit from Eric Berry after a 4-yard catch, profootballtalk.com reported.
JAGUARS: Running back Maurice Jones-Drew, who missed three days of practice this week, didn't make the trip to Tampa for tonight's preseason game against the Bucs. Jones-Drew's agent, Adisa Bakari, said the team is resting the Pro Bowl pick in the final two preseason games for "precautionary reasons."
LIONS: Defensive end Jared DeVries went on injured reserve, meaning he will miss a second consecutive season because of injury. He had arthroscopic surgery on his left knee this week.
RAMS: Wide receiver Donnie Avery tore his right ACL on Thursday against new England and is out for the season, coach Steve Spagnuolo said. Avery led the team with 47 receptions last season.
