That was the case once again on Thursday after reports broke that the Raiders were thinking about suspending Brown due to an altercation that almost got physical between Brown and Raiders' general manager Mike Mayock.
According to Schefter, Brown's Instagram post led to an exchange, which will result in further discipline.
Ian Rapoport of the NFL Network tweeted: "It did not get physical, sources say".
The tensions reportedly escalated after Brown shared his apparent displeasure with Mayock for sending him a letter about the possible fines the wide receiver faces for missing a practice and a walkthrough.
When your own team wants to hate but there's no stopping me now the devil is a lie.
The 31-year-old Miami native incurred frostbite on his feet during a botched cryotherapy session in France, leading to Brown getting placed on the non-football injury list.
After the first absence, Mayock issued a statement saying the Raiders needed to know if Brown was "all-in or all-out" after an offseason of issues. He had been using a Schutt Air Advantage helmet that no longer is approved by the league.
Brown wasn't pleased with the letter, judging by his response.
Brown has been unable to stay away from drama since last season.
The Raiders acquired the seven-time Pro Bowl selection from the Pittsburgh Steelers in a trade in March and later signed him to a three-year, US$50.1-million contract.
Brown caught at least 100 passes and exceeded 1,200 receiving yards in each of the past six seasons with the Steelers.
