At least three NFL head coaches have been fined $100,000 for violating the league’s rules that they wear face coverings on the sideline including Seattle’s Pete Carroll. Their teams were fined $250,000. More fines could be coming as several other coaches violated the league’s rules requiring coaches to wear coverings over their mouths and noses at all times. Players are exempt from these protocols. Among the violators were Patriots coach Bill Belichick.
