Antonio Brown is not going to let this go.

After finding several helmets that were Schutt AiR Advantage and under 10-years-old, the NFL would have them tested to see if they were good, and they all promptly failed.

On Monday, the Oakland Raiders WR refused to let the matter go as he filed a new grievance against the NFL over wearing the helmet.

Raiders GM Mike Mayock has already spoken out about Brown being “all in or all out” because the team had already exhausted every avenue to get him the helmet he wanted and it still did not work.

Now, Brown goes back to the drawing board to try one more time.
