Following a year of hand-wringing and disagreement inside the league’s ownership ranks, team owners approved a new measure on Wednesday that gives players the option of staying in the locker room during the national anthem if they don’t wish to stand during the ceremonies. Under the new rule, players who choose to be on the field during the anthem will be required to stand. If a player or team employee is on the field during the anthem and chooses not to stand, that player’s franchise will be fined by the NFL. In turn, players and employees who choose to attend the anthem ceremonies but do not stand will also be eligible for a fine by their franchise, if the team chooses to levy one.
