The NFL is recommending that players on the sidelines who are not participating in a game or about to go on the field wear protective masks, according to a league management council memo obtained by The Associated Press on Friday, Oct. 30, 2020. Although the NFL stopped short of mandating masks for all players not on the field, it “strongly encouraged” all active players in the bench area who are not about to enter the game to wear masks while standing on the sideline and/or sitting on the bench.
