The NFL has heard Antonio Brown and is not bending.

On Monday, league spokesman Brian McCarthy addressed the current situation involving a certain Raiders receiver on Twitter without referencing Brown by name.

“The player can’t practice or play in games with equipment that’s not approved. 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 NOCSAE [the National Operating Committee for Standards and Athletic Equipment]. They don’t certify equipment that’s old than 10 years,” McCarthy posted.

Last week, Brown threatened to quit football if he was unable to wear his desired helmet. Raiders coach Jon Gruden defended his lightning-rod receiver Saturday.

“There’s been a lot of reports out there. I can’t say I agree with all of them, certainly, but I support this guy. I think that’s what needs to be said,” Gruden told the media.

“He has a strong feeling about what he’s worn on his head, and we’re supporting him. We understand the league’s position as well, so we’re in a tough spot,” the coach later stated.

As for Brown, who is also dealing with burns to his feet as a result of not wearing proper shoes in a cryotherapy machine, he’s posted cryptic messages on social media as the bizarre ordeal continues to unfold.

“I love the game; I love the hustle; young-in got doe he can leave the league but if I leave will the fans still gone love me man? #paidinfull,” Brown wrote Friday.

He followed up with another note Sunday, posting, “‘Pollitoooo Wolves don’t loose sleep over the opinions of sheep.'”
