Eden Prairie, Minn. ? Out with the new, in with the old.

With the passing offense sputtering in two losses to open the season, Minnesota coach Brad Childress decided the Vikings can no longer afford to let 25-year-old quarterback Tarvaris Jackson learn on the job.

On Wednesday, Childress turned to 15-year veteran Gus Frerotte to run the offense for the rest of the season.

“I’m just not seeing right now the aggressiveness from Tarvaris that I saw throughout the offseason, training camp, the two preseason games that he played in,” Childress said. “And part of it may be experience. I know Gus will give us that. And I know his approach will also lend itself to that.”

Jackson completed just 51 percent of his passes this season. He threw a game-ending interception at Green Bay that sealed the Packers victory and was partly responsible for the offense settling for five field goals and scoring no touchdowns in an 18-15 loss to the Colts.

“I know there’s many other plays, there’s a lot of other people that have to step up,” Childress said. “But then when you go back through and look at the tape, and most importantly to be able to sit across from the young man and want to be able to verify what you’re feeling – it’s kind of like looking in your kids’ eyes and saying one (thing) and feeling another.”
