Winfield was notified of the fine Thursday. The play happened in the second quarter when Winfield rushed on a blitz. The 5-foot-9 cornerback went to tackle Cutler, and his helmet hit the quarterback in the chin.
Winfield's agent, Ashanti Webb, told the St. Paul Pioneer Press that Winfield was fined an additional $10,000 for a uniform infraction involving the height of his socks.
Cutler needed stitches to close the wound, but remained in the game. He threw three touchdown passes in a 40-14 victory over the Vikings that clinched the NFC North title for Chicago.
Winfield has long been known as one of the most physical cornerbacks in the league. But he is rarely fined for hits and considered among the league's most fundamentally sound tacklers.
The Pioneer Press reported that Winfield will appeal the fine for the hit.
