Most NFL team facilities will be closing for two days to prevent the spread of COVID-19.
A memo from commissioner Roger Goodell says all team facilities will be closed to in-person activities today and tomorrow.
When announcing the move, officials say they know a number of players and staff members celebrated the American Thanksgiving holiday with out-of-town guests.
Players are being asked to inform their teams if they had guests over for the holiday.
Teams playing today and tomorrow are exempt from the closures.
