Although the NFL announced on Tuesday that there will be no preseason games in 2020, the league also said if there are NFL games this fall, and if fans are allowed to attend in person, face coverings will be required due to the coronavirus pandemic.

The decision comes with the likelihood of teams playing in front of no or a limited number of fans during the regular season. Several states have said that large gatherings will be limited into the fall.

Team training camp is set to begin at the end of the month, where players and coaches will be tested for coronavirus in addition to other measures to keep people safe. There are still details being worked out about procedures at training camp between the league and players’ union.
