The National Football League announced Wednesday it will require fans to wear facial coverings at in-person games this season.
In a tweet, NFL spokesperson Brian McCarthy said the policy is league-wide.
Some NFL teams had already required the masks. This latest rule change extends the mask mandate to all 32 teams.
In addition to requiring facial coverings, attendance will be reduced at stadiums as coronavirus cases and deaths continue to rise in the country.
The comments come a day after President Donald Trump at the reinstated White House coronavirus briefings, called wearing a face mask "patriotic".
