Antonio Brown should have his own 24/7 news channel this preseason.

The Raiders star receiver took part in a portion of one practice during training camp due to frostbitten feet that have not yet fully healed. Then, of course, there's the whole helmet issue.

Brown continues to be upset at the NFL's policy that he wear a helmet that is up to the safety standards set by the league. His preferred Schutt AiR Advantage was put on the prohibited list because it allows the brain to feel around 40 percent more force of impact than the latest improved models. The seven-time Pro-Bowl receiver missed practice Sunday, leading general manager Mike Mayock to deliver a public ultimatum that AB be "all-in or all-out."

Brown was back with the team at a meeting Monday. He filed a second grievance with the NFL on Monday to have a 12-month grace period to wear his helmet.

This is all gold for HBO as they continue to follow the Silver and Black on "Hard Knocks." Brown has spoken to the media for just a few minutes during camp, but he, of course, broke his silence for the cameras as seen in the latest clip for the third episode which airs Tuesday.

"The feet feeling a lot better," Brown told the cameras. "I got brand new skin. Got it all trimmed up. It's been a journey, man, but I feel a lot better. Working with the NFL. Getting the right equipment. I been working hard on the side. I been going, taking care of the feet. I want to give it to my teammates, so hopefully, soon get out there and get to work.

"You know, too much noise right now. More work, less noise. I feel like I was enemy of the f--king state. F--k! Getting the feet trimmed up.  I'm on every channel. Because AB is actually a good player. A really good player. And he's a handsome looking player, by the way. So that's all it is right there."

All right.

Brown could stop all the noise by getting on the field, or at least being with his teammates while the helmet issues gets sorted out, but he knows that. The attention is on him, and clearly that's the way he likes it.

Brown looked to be running smoothly when he went through warm-ups prior to the Raiders' preseason win over the Cardinals. By his own admission and Instagram activity, the feet appear to be close to ready to go.

One issue down. One to go.
