NFL Commissioner Roger Goodell has no qualms about harshly penalizing coaches who violate the NFL’s protocols mandating that they wear facemasks while roaming the sidelines.

The NFL on Monday fined three coaches – San Francisco’s Kyle Shanahan, Denver’s Vic Fangio and Seattle’s Pete Carroll – a $100,000 each for disregarding the policy. Additionally, their respective teams were docked $250,000 apiece.

“It’s consistent with the message,” Goodell told USA TODAY Sports on Monday night. “You can’t let up. We’ve got to consistently do the things that have gotten us to this place and not think, ‘Okay, things have gone so well, so it’s okay now.’ It’s not. You’ve got to stay on your toes and we’ve got to continue to be disciplined.”

Through training camp and two weeks of the regular season, the NFL has been successful in preventing the spread of COVID-19 within its ranks and hasn’t experienced outbreaks with any of its 32 teams that potentially could disrupt the season. It’s a credit to strict protocols and daily testing instituted by the leagueand the NFL Players Association. According to ESPN, since the start of training camp Aug. 12 until Sept. 12, the latest date for which there is data, a total of seven players and 24 other personnel have produced positive confirmed tests.
