Sports briefs: Peterson out vs. Raiders

A week after becoming the talk of the NFL with the best single-game performance in league history, Minnesota Vikings running back Adrian Peterson’s season is in peril. The rookie has a torn lateral collateral ligament in his right knee. He has been ruled out of Sunday’s game against the Raiders. Also, Vikings quarterback Tavaris Jackson is returning this week following a concussion.

Another change for Raiders?

The revolving quarterback door for the Raiders might be taking another turn this week. Coach Lane Kiffin did not commit to Josh McCown making a second consecutive start when the Raiders travel to Minnesota on Sunday. With McCown under center, the Raiders netted just 80 yards passing in losing 17-6 to the Chicago Bears and completed only one pass during a 29-minute stretch that began late in the second quarter. “When you’re not productive, it’s usually not one person,” said Kiffin, refusing to lay all the blame on McCown for the lack of production. “He was inaccurate, he didn’t have much time, and we weren’t making many plays for him.” While fans are clamoring for No. 1 overall pick JaMarcus Russell to play, Kiffin could go back to Daunte Culpepper, who began his career in Minnesota. Culpepper excelled when he faced his other former NFL team, Miami, this season.
