NAPA, Calif. — Following Antonio Brown lost his grievance against the NFL over wearing his old helmet, then that the Oakland Raiders receiver needs to come back to the team’s training camp soon. Brown continues to be dealing with frost bitten feet suffered within an cryotherapy accident in France a month. He have not been with the Raiders since being limited in a clinic and leaving early on July 30.

It is recognized as”most unlikely” that Brown will appeal your decision,” a source told ESPN’s Adam Schefter.

Brown wants to use his older helmet, believed to be a 10-year-old Schutt Air Advantage version, which is now not made by the company and, ergo, no longer certified by the National Operating Committee for Standards and Athletic Equipment. He’s tried the newest certified helmet out and considers it protrudes out and interferes with his vision as he tries to catch the football.

On Friday, Brown had a two-hour conference telephone with a completely independent arbitrator to assert he should be permitted to use his helmet that is older, he is thought to have already been using his whole career. The arbitrator for the grievance telephone was joined by league officers, participant representatives and NFLPA representatives in Philadelphia, a source told ESPN.

Brown claimed his helmet made him feel safe and, save to an illegal hit from Vontaze Burfict at the 20-16 play-offs, kept him a source told ESPN’s Jeremy Fowler. The arbitrator was sympathetic but issued that which was described by a source as a”very kind jobless.”

Raiders coach Jon Gruden said he supports the participant that opened camp on the non-football injury list, and it has engaged in a single pre-practice walkthrough, on July 28, before being limited on July 30. The Raiders have held 11 clinics and one demo game.

“He has a solid feeling of what he’s worn in his mind, and we’re encouraging him,” Gruden said after Saturday’s exhibition against the Los Angeles Rams. “We understand that the team’s standing as well, thus we’re at a tough spot, and we expect Antonio will be here now because he is exciting to worry about. I’m excited. I have some plays . I expect we can begin calling them.”

Brown, acquired by Oakland at a trade to get a third- and a fifth-round pick in March from the Pittsburgh Steelers and instantly given a three-year, $50.125 million contract, has threatened to retire if not allowed to wear his helmet.

“I’ve got a lot of confidence he’s one of the greatest competitors whom I’ve been around,” Gruden said. “And I have a sense he’d play no helmet that’s how much he likes to perform . But I’m not likely to put words in anybody’s mouth. We’re going to encourage himand whatever his decision is, we will stand by it. But we’re convinced he’s likely to become a huge element for the Raiders for decades in the future .”

Additional NFL players not satisfied to change helmets include tombrady and Aaron Rodgers, along with a”couple” of most Raiders players, even per a league source, although none had threatened to retire just such as Brown.
