The NFL has already ruled at least one 9/11 tribute out of bounds on opening weekend.
Titans linebacker Avery Williamson has been told to shelve a pair of cleats he planned to wear to commemorate the 15th anniversary of the September 11 attacks. Williamson was informed by the league he would be fined for a uniform violation if he wore the shoes.
Giants receivers Odell Beckham and Victor Cruz wore similar shoes. Other players, including the Falcons’ Julio Jones, wore similar cleats during warms-ups.
