Wide receiver Antonio Brown has filed a complaint with the league because he is not allowed to use the helmet he wants. The model, which he has used throughout his entire career, is too old and no longer allowed for safety reasons.

The Raiders have given him several new models to test, but none have gone down in taste.

And according to ESPN, the discontent is much greater than that. Brown has left the team's preseason and is said to have said he will not return until he is allowed to use his favorite helmet, the site writes.

"He asked for his old helmet but was told that he needed to use a permissible model, and then clearly and loudly expressed his displeasure. Shortly thereafter, he stormed out of the facility, ”says Mike Silver at NFL Network.

“The next day he appeared as if nothing had happened and used the right helmet. But the week after, he went out on the pitch in his old Pittsburgh helmet which he had painted in Raider's silvery and black design. "

Brady has also complained

According to Mike Silver, Oakland has had major problems with Antonio Brown, who has been delayed several times, used the mobile phone during meetings and refused to communicate with leaders in the team.

New England Patriots big star Tom Brady is another player who has complained about the NFL's new strict rules on helmets.
