Oakland Raiders star Antonio Brown lost his second grievance against the National Football League over their ruling that he could no longer use an old helmet due to its age, according to NFL.com.
NFL.com writes: “Brown’s hearing this past Friday involved the same independent arbitrator as his first hearing. The All-Pro wideout argued he should be given a one-year grace period to phase out using his helmet. Brown has not played in the preseason while dealing with the helmet issue and a foot injury.”
Mercury News reports that Brown was on the field Sunday practicing with teammates.
