The league stated "accountability measures" will be required for those who don't adhere to the rules, while ESPN's Adam Schefter reported fines will be in play.
The NFL has instituted strict protocols surrounding the COVID-19 pandemic, including rigorous testing, but the league cleared about 5,000 players, team personnel and game-day assistants before Sunday's games, per Schefter.
