Minnesota Vikings defensive end Jared Allen was fined $21,000 by the NFL for his hit on Chicago Bears guard Lance Louis, multiple media outlets reported Wednesday. As a result of Allen's blindside hit on Sunday, Louis tore his anterior-cruciate ligament and was placed on injured reserve Monday. The hit occurred after Vikings cornerback Antoine Winfield intercepted a pass. Louis was turning toward Winfield to make a tackle when he was hit by Allen, who was attempting to block. Allen later said he thought it was a legal hit. Louis has started all 11 games this season. Allen was not suspended, so he will play in the Vikings' next game.
