It took less than a day for the NFL to respond to Antonio Brown's apparent plan to get the league to allow him to continue using a helmet that is no longer an approved model by the league. The NFL's response, issued by spokesman Brian McCarthy, essentially boils down to: "That's not how this is gonna go."
"The player can't practice or play in games with equipment that's not approved," McCarthy said, clearly referencing Brown even if not specifying him by name. "If he doesn't play or practice he is in breach of his contract and doesn't get paid. NFL policy is that Helmets have to be certified by NOSCAE. They don't certify equipment that's old(er) than 10 years."
