UPDATE: Brown Files New Grievance Over Helmet – Oakland Raiders wide receiver Antonio Brown has filed a new grievance against the NFL in an attempt to be able to wear the helmet he wants, a source told ESPN’s Adam Schefter. This grievance is the latest part of Brown’s ongoing fight against an NFL policy that requires helmet certification according to industry standards. Brown already lost a grievance against the NFL that sought an exception so he could wear his Schutt Air Advantage, a helmet he has worn throughout his career. He believed last week that he had found a suitable replacement, but that particular helmet was not certified according to the standards of the National Operating Committee on Standards for Athletic Equipment (NOCSAE). Brown’s agent, Drew Rosenhaus, said Monday that the star receiver’s helmet concerns are safety-related. General manager Mike Mayock said Sunday that Brown had left camp over the helmet issue, and it was “time for him to be all-in or all-out.” Rosenhaus disputed that Brown had left camp, and the wideout was back with the team at the facility on Monday morning, a source told Schefter. The Raiders acquired Brown in a trade with the Pittsburgh Steelers in March, then signed him to a three-year deal worth $30.125 guaranteed. I hope he can get past this; its for his own protection. Lets move on.
