Uniform Fines:
NFL player fine money is split evenly among four organizations: the Brian Piccolo Cancer Fund, the Vincent T. Lombardi Cancer Research Center, ALSO Neuromuscular Research Foundation and the NFLPA Player Assistance Trust.
The number of players fined on any given week for uniform violations varies from as few as 5 or 6 to as many as 75 to 100.
The NFL collects fines immediately and then returned after an appeal or settlement.
Players can and usually do appeal, and the fines are sometimes reduced or rescinded.
Any player who is fined for uniform or equipment violations may contact the NFLPA legal department or his team's Regional Director at the NFLPA to appeal the fine. Players generally have ten days to appeal such fines.
Fines range from $5,000 to $25,000. Wearing a college hat on the field is an example of a $25,000 violation.
Foreign Substances on Body/Uniform is $10,000 or $15,000 (Additional fines may be imposed on team management and coaching staffs for condoning, permitting, etc., violations in this area.)
Other Uniform/Equipment uniform violation is $5,000 or $10,000
On Field Preseason and Regular Season uniform violation is $10,000 or $20,000
Playoffs (Including Pro Bowl) uniform violation is $50,000 or $75,000
