Team workers must wear masks for the duration of the game. Failure to comply might result in a fine and/or suspension, according to the NFL. According to ESPN, five coaches have been fined $100,000 each (their teams $250,000) for neglecting to wear face masks during games. The most serious infraction so far was by Gary Anderson, who coaches the Seattle Seahawks' defense. After one of his players was injured on a play against the New York Giants in September, Anderson refused to put on a mask. "I'm not going to wear a facemask," he said. "I'm not going to do it." He was fined $200,000 ($400,000 if he had refused to wear a helmet). Coaches are required to wear protective headgear at all times while on the sideline. However, they do not need to wear a facemask unless they are taking part in the coaching staff's huddle program. If they choose not to participate, their assistants can be given different assignments during timeouts or other critical moments of the game. In addition, defensive coaches are expected to instruct their players from behind a shield during games. But this rule is rarely enforced. One reason may be that many defenses use a 3-4 alignment that does not require a secondary coach to be positioned behind his players. There is no penalty for NFL players who fail to wear masks.
