Raiders GM Mike Mayock Sends Stern Message To Antonio Brown After Skipping Practice Again Over Helmet Issue

Mike Mayock and the Oakland Raiders are already fed up with Antonio Brown and his helmet.

Earlier this week, Brown was denied the right to use an Schutt Air Advantage helmet that was under 10 years old.

Because of that ruling, Brown was upset and once again skipped practice.

That didnt sit well with the Raiders front office and on Sunday, Raiders GM Mike Mayock issued a stern warning to Brown to be “all in or all out” because the franchise has “exhausted all avenues” on this helmet issue.
