The NFL was the first major professional league in North America to say goodbye to all rules for dealing with the corona virus.
Since the decision, teams no longer have any restrictions, no longer have to test anyone or ensure that masks are worn.
Football teams only have to comply with them on their facilities if regional regulations are still in force. However, the season has been over since the Super Bowl in February and the pros are currently not seeing each other for joint training sessions with their teams anyway.
