EDEN PRAIRIE, Minn. (AP) — Minnesota Vikings defensive end Jared Allen has been fined $21,000 for a hit on Chicago Bears guard Lance Louis on Sunday.

A person with knowledge of the fine tells The Associated Press that it was levied Wednesday, three days after he knocked Louis out for the season with a hit that injured Louis' left knee. The person requested anonymity because the league has not announced the fine.

Allen hit Louis after an interception by Antoine Winfield. Louis didn't see Allen coming, and his leg stuck in the turf on the hit and tore the ACL in his left knee. Several Bears, including coach Lovie Smith, said they thought the hit was unnecessary and dirty.
