Cincinnati Bengals linebacker Vontaze Burfict was fined $31,000 by the NFL on Friday for two unnecessary roughness violations.
Burfict had hit defenceless Packers receiver James Jones in the head and neck area, which cost him $21,000, and then struck Green Bay tight end Ryan Taylor, costing him $10,000.
Bengals teammate George Iloka was fined $15,000 for unnecessary roughness when he struck a defenceless player, tight end Jermichael Finley, in the head and neck area.
Steelers wide receiver Antonio Brown received $15,750 in fines for two unnecessary roughness violations: $7,875 for a late hit on Bears safety Chris Conte, and $7,875 for a face mask on Sherrick McManis.
Titans linebacker Moise Fokou was docked $7,875 for unnecessary roughness for a face mask violation.
The NFL also fined Panthers quarterback Cam Newton $10,000 for wearing clips on his helmet visor featuring the Under Armour logo.
Although the clips that attach Newton's clear visor to the helmet are small and difficult to see, the league considers it a violation of its equipment policy.
NFL rules state that "No visible identification of a manufacturer's name or logo on the exterior of a helmet or on any attachment to a helmet is permitted unless provided for under a commercial arrangement between the League and manufacturer."
Nike has a signed contract to be the NFL's equipment provider. Newton is one of Under Armour's main clients.
The violation was first pointed in an article Tuesday by Forbes.com.
