Bowl receiver to them for such a low price.Since he joined the Raiders http://www.ravensfootballauthentics.com/justice-hill-jersey-authentic , Antonio Brown has frustrated his new team by showing up late to numerous meetings and then often appearing unfocused in them, according to Michael Silver of the NFL. Brown is distracted by several tablets and his cell phone during meetings, checking his bank accounts and perusing Instagram, Silver reports.That’s not even the biggest issue, though.“The meeting thing isn’t that bad,” a source told Silver, “but the feet, helmet and going dark is an issue.”Although a report earlier Friday said Brown is expected to rejoin the Raiders at training camp “sometime in the near future,” Brown’s issue with his helmet, which prompted him to file a grievance, apparently is what has kept him from Napa since late last week. It also caused him to storm out in protest during an organized team activity Ben Powers Jersey , according to Silver.“He’s still freaking out about it,�? an unnamed Raiders player told Silver. “He hasn’t been here for awhile, and no one knows where he’s at.”Even before injuring his feet in a cryotherapy chamber, Brown’s resistance to complying with the NFL’s enhanced enforcement of helmet regulations “alarmed” coaches and teammates, per Silver. Team officials continually have told Brown he can’t wear his old helmet, which PFT has reported is just that — too old.Brown continues to protest either verbally or by refusing to wear the new helmet.“Honestly, the most insane thing I have ever heard,” a source told Silver. “I don’t know why it’s so important to him. It doesn’t make any sense.�? Brown, who has worn the same helmet for his entire career, initially was told in May that he would have to switch to a new helmet. Brown, though http://www.ravensfootballauthentics.com/iman-marshall-jersey-authentic , complained at the first organized team activity that he was being singled out. He stormed out of the facility, with team officials texting Brown video footage of Aaron Rodgers, who also has to change helmets, in an approved model.Brown returned the following day and “acted like nothing had happened.” He practiced with the new helmet.Days later, however, Brown again tried to wear his old helmet, which he repainted with colors“approximating — but not completely mimicking — the Raiders�? silver-and-black design,” according to Silver. Brown complied, wearing a new model after team officials again told him his old helmet was banned.The Raiders believed the issue was resolved when training camp began, but Brown arrived on the practice field with his old helmet.Brown is expected to have a hearing on his grievance next week.Meanwhile, whether it’s his feet or the helmet issue Trace McSorley Jersey , Brown hasn’t participated in a full practice during camp and has taken part in only one of the Raiders’ 11 sessions. Hard Knocks addressed none of the Brown saga during Tuesday’s premiere and made no mention of what is medically wrong with Brown’s feet, saying only the star receiver “is hobbled by injuries to his feet.” Training camp goes up a notch for the Raiders on Wednesday, but the team’s biggest free-agency arrival won’t be there for it.As noted by Michael Gehlken of the , receiver Antonio Brown remains absent as the Raiders welcome the Rams for two days of joint practice. It will be the eighth practice that Brown has missed, due to feet that were frozen by entering a cryotherapy chamber without proper footwear.“It’s good to go against a different scheme,” quarterback Derek Carr said regarding the joint practices, via Gehlken. “I really enjoy it and especially when it’s two really professional teams that aren’t trying to prove their manhood or prove their toughness to each other. Obviously, football is a physical game, but when there are just fights and brawls, I think that’s pointless.”Five years ago, during Carr’s rookie season Kyler Murray Jersey , the Raiders and Cowboys got into a knock-down-drag-out fight during training camp at Oxnard, California. The following year, the Rams and Cowboys rumbled in Oxnard. Raiders coach Jon Gruden and Rams coach Sean McVay, who worked together in Tampa and who remain good friends, surely will try to avoid any joint-practice ugliness.The Raiders and Rams will meet in a preseason game on Saturday night in Oakland. Brown surely won’t be playing. Although his condition has been downplayed by the Raiders, it’s clear that it’s not minor. At some point, the Raiders need to start worrying about whether he’ll be available for Week One — and if so whether he’ll be effective.
