The Raiders signed Brown to a big extension this offseason but it's pretty clear they are already sick of the antics that surround him.
On Wednesday, Brown posted an image of a letter he received from Raiders general manager Mike Mayock informing him that he had been fined $13,950 for a missed practice.
The Raiders are now five days away from their season opener but still dealing with Brown's drama.
Brown missed much of training camp this summer because of frostbitten feet and because he was unhappy that National Football League safety regulations now prevent him from wearing the helmet he had worn his entire career.
"As you know, you did not participate in the Raiders walk through on August 22". The letter also indicates that Brown had already been fined $40,000 for missing a training camp practice on August 18, which was the same day Mayock issued his very public "all-in or all-out" ultimatum to Brown.
In the post, Brown wrote, "When your own team want to hate but there's no stopping me now". We've got 89 guys busting their tails.
Brown also publicly feuded with former Pittsburgh Steelers teammate Ben Roethlisberger after the quarterback said he regretted his "ruined friendship" with Brown.
Brown's message continues one of the most weird preseasons from a star player in recent memory.
From his frostbitten feet to an old helmet and now his pocketbook, it never stops with Antonio Brown.
The Raiders sound as if they're losing some patience, but a stellar season, like those Brown has routinely delivered, would go a long way toward restoring their happiness with a player for whom they traded 2019 third- and fifth-round picks and gave a reworked contract that could pay him as much as $54.1 million over the next three years.
