Jacksonville Jaguars defensive tackle Terrance Knighton, Kansas City Chiefs linebacker Tamba Hali and New England Patriots linebacker Brandon Spikes were fined $25,000 US each by the NFL on Friday for hits in recent games.

Knighton was fined for making helmet-to-helmet contact with Indianapolis Colts quarterback Andrew Luck, who was defenceless at the time. The hit came in Indianapolis' victory Nov. 8 against the Jaguars in Jacksonville and negated an interception by Aaron Ross.

Hali was docked for striking Pittsburgh Steelers quarterback Byron Leftwich with his helmet.

Spikes got a roughing-the-passer penalty on Buffalo Bills pivot Ryan Fitzpatrick that drew the fine. He hit Fitzpatrick with his helmet. The players later jawed at each other and after the Patriots' win, Fitzpatrick called Spikes "a punk."

In all, 17 players drew fines Friday for their actions in Week 10 games.

Oakland Raiders linebacker Aaron Curry was given two fines: $15,750 for striking Baltimore Ravens running back Ray Rice late, and $7,875 for unnecessary roughness on a special teams play. Raiders linebacker Phillip Wheeler was fined $7,875 for unnecessary roughness when he grabbed Rice by the facemask.

Fined $21,000 were San Francisco 49ers defensive lineman Ray McDonald for a helmet-to-helmet hit on St. Louis Rams quarterback Sam Bradford last Sunday, and Minnesota Vikings linebacker Jasper Brinkley for a helmet hit on a defenceless Calvin Johnson, wide receiver for the Detroit Lions.

AFC players fined that amount were Denver Broncos linebacker Von Miller for striking Carolina Panthers quarterback Cam Newton below the knee; and Colts defensive end Jerry Hughes for a late hit on Jacksonville pivot Blaine Gabbert.

Docked $15,750 were Cincinnati linebacker Rey Maulaluga for striking defenceless New York Giants wide receiver Dominek Hixon in the head and neck area; and Denver defensive tackle Kevin Vickerson for a horse-collar tackle on Newton.

Jaguars safety Dawan Landry was fined $10,000 for a fourth-quarter hit on Luck that made contact to the head and neck area after Luck declared himself down by sliding feet first. Lions receiver Ryan Broyles was fined $10,000 for an illegal crackback block on Vikings cornerback Antoine Winfield.

Others docked $10,000 were Patriots linebacker Jerod Mayo for a late hit on Bills running back C.J. Spiller when he was out of bounds; and Miami Dolphins guard Richie Incognito for striking Tennessee Titans linebacker Colin McCarthy late. Incognito was benched for a few plays by Dolphins coach Joe Philbin after the incident.

Justin Houston of Kansas City was fined $7,875 for unsportsmanlike conduct when he began a group celebration in the end zone. Patriots cornerback Alfonzo Dennard lost the same amount for hitting Fitzpatrick out of bounds.
