PITTSBURGH (KDKA) — According to new reports, the Oakland Raiders are now getting a taste of what Pittsburgh Steelers fans have been dealing with for years.

First it was extreme frostbite on his feet, which has held him out of most of training camp.

Now comes a new report about Antonio Brown’s bizarre behavior at Raiders training camp.

ESPN’s Adam Schefter reports that Brown has told the Raiders that unless he gets his old style football helmet, he won’t play in the NFL again.

And now this: Raiders’ WR Antonio Brown has told team officials that, unless he gets to wear his old helmet, he will not play football again, per league sources. And more…. — Adam Schefter (@AdamSchefter) August 9, 2019

He reportedly even had a two-hour long meeting with NFL officials regarding the helmet.

NFL columnist Michael Silver posted a tweet thread of 20 different tweets about Brown’s antics.

They include him reportedly “freaking out” about a new helmet that has been mandated in the NFL, because it’s safer.

At one point Silver says Antonio actually painted one of his old banned helmets to “mimic” a Raiders helmet.
