Known for posting things he shouldn’t from his days in Pittsburgh, Brown posted his fine letter sent by general manager Mike Mayock on Instagram.
According to Paul Gutierrez from ESPN, Brown was half-hearted at practice that day and was barking at the strength coach before eventually getting into it with Mike Mayock.
The altercation was described as very ugly to the point where Vontaze Burfict had to hold Brown back. There was also a bevy of cuss words thrown at Mayock by Brown.
