Here's something you don't see everyday: Oakland Raiders wide receiver Antonio Brown has filed a helmet grievance against the NFL, according to Adam Schefter of ESPN.
The helmet Brown wore throughout his first nine NFL seasons with the Pittsburgh Steelers, which is believed to be the Schutt Air Advantage helmet, is no longer certified by the National Operating Committee for Standards and Athletic Equipment.
Therefore, NFL players are no longer permitted to wear that specific headgear, and Brown, who is comfortable with that model, would prefer to stay with what he knows.
Brown's hearing is expected to take place as early as next week.
This is just the latest story in what has been an offseason full of them for Brown.
First, the 31-year-old requested a trade from the Steelers after a late-season fallout with Ben Roethlisberger and Pittsburgh's organization, which resulted in Brown being benched for the team's season finale.
The Steelers granted his request, sending him to the Raiders for a third-round draft pick and a fifth-rounder.
Brown participated in Oakland's voluntary offseason workouts and mandatory minicamp and also arrived in time for training camp, showing up to Napa Valley via hot air balloon.
However, the seven-time Pro Bowler was then placed on the non-football injury list. He was on the list for less than 48 hours before practicing with the Raiders, but he only partially participated and has not practiced since due to a foot issue.
It was later revealed that Brown's foot problem developed as a result of getting frostbite while in a cryotherapy chamber. There is currently no timetable for his return,
