Antonio Brown lost the second grievance he made against the NFL over being allowed a one-year grace period to phase out the helmet he has been wearing his entire career, Ian Rapoport of NFL.com reports.
The Raiders wide receiver filed his first grievance against the league at the start of this month. He had missed time during training camp after suffering "extreme frostbite" on his feet, but his continued absence revealed that changing helmets was his main hold up before returning to practice.
It was reported that Brown would not play football if he was not allowed to continue wearing his Schutt AiR Advantage helmet.
