NFL Commissioner Roger Goodell sent out a memo to all 32 teams regarding the league's coronavirus safety protocols, and he made clear there will be penalties for violations.

In the memo, which was sent to teams after a conference call on Monday involving NFL and club executives, Goodell restated that everyone needs to follow the health and safety guidelines passed down from the league.

10 RAIDERS PLAYERS FINED FOR COVID-19 VIOLATIONS

“Protocol violations that result in virus spread requiring adjustments to the schedule or otherwise impacting other teams will result in additional financial and competitive discipline, including the adjustment or loss of draft choices or even the forfeit of a game,” Goodell wrote in the memo, obtained by the Associated Press. “Simply put, compliance is mandatory. Now is the time to recommit ourselves to our protocols and best practices for the duration of the season.”

There are other consequences caused by rescheduling ormissing games he said.

"Our fans will be deprived of games," Goodall said. "Competitive inequities will be introduced into our season. Players will not be paid for games not played and clubs will similarly suffer financial consequences.”

Goodell mentioned that many violators have already been punished.

A few coaches have been fined $100,000 each, and their teams were fined $250,000 for not wearing face masks properly. Denver Broncos' Vic Fangio, San Francisco 49ers' Kyle Shanahan and Seattle Seahawks' Pete Carroll were docked $100,000 each. New England Patriots coach Bill Belichick, Jon Gruden of the Las Vegas Raiders and Sean Payton of the New Orleans Saints were all disciplined as well.
