Brown posts video featuring audio from apparent phone call with Gruden

Warning: Story/video contains coarse language

Amid reports he's unhappy with the fine handed down by the Oakland Raiders for his recent altercation with general manager Mike Mayock, Antonio Brown posted a video on his YouTube channel Friday containing audio from what seemed to be a phone call with head coach Jon Gruden.

"I've been trying to be a Raider since Day 1, I've been fucking working my ass off harder than anyone," Brown told Gruden in the audio clip. "I don't know why it's a question of me being a Raider. It's like, do you guys want me to be a Raider?"

An apparent reply from Gruden followed.

"Please stop this shit and just play football," he said. "How hard is that?"

The Raiders have yet to comment on the video. It's currently unclear when the conversation took place and who recorded the audio. If Brown recorded it, the question will be whether he had Gruden's permission to do so.

A team source told ESPN's Chris Mortensen the head coach was amused by the video and thought it was "awesome."

"You're not a villain," Gruden said in the recording. "You're the most misunderstood fucking human being in my entire life that I've ever met ... I don't know where you are in your life right now off the field. All I know is you got a lot of things going. There's a lot of people that have an opinion about you, and whether it'd be good or bad, you're in the spotlight all the time."

The conversation could refer to a number of incidents, including Brown's helmet issue, his frostbitten feet, or his decision to post an earlier fine letter from the Raiders to social media.

"I'm more than just a football player, man," Brown said near the end of the clip. "I'm a real person. It ain't about the football, I know I can do that."

Gruden announced earlier Friday the star wideout had been cleared to play in Oakland's season opener after apologizing to Mayock and the team.
