NFL fines Tyrique Stevenson $22,342 for hit that knocked off Aaron Jones's helmet

The NFL imposed a $22,342 sanction on Bears defensive back Tyrique Stevenson for impermissible use of the helmet. The rulebook prohibits a player from lowering his head and making forcible contact with his helmet against an opponent.

The infraction was not flagged; it rarely is. Typically, the situation is addressed with the imposition of a fine.

Impermissible use of the helmet is not one of the five violations that will result in an automatic suspension if there are three violations.
