12:41 PM PT -- ANTONIO BROWN JUST UNFOLLOWED THE RAIDERS AND DEREK CARR ON INSTAGRAM!!!! (hat tip Dov Kleiman).
11:28 AM PT -- Mike Mayock just gave a 15-second press conference about the ongoing drama with the superstar receiver ... and while he didn't say much, his demeanor spoke volumes.
“Antonio Brown is not in the building today. He’s not going to be practicing. I don't have any more information. When we do, I’ll get it to you. That’s it for today."
10:37 AM PT -- This is getting insane!!! Brown never got physical with Mayock but allegedly threatened to "hit him in the face," according to NFL Network's Ian Rapoport.
Then, Brown allegedly punted a football and told Mayock, "Fine me for that!"
Yeah, this is not good.
9:51 AM PT -- During the exchange with Mayock, Brown reportedly had to be "held back by a couple of teammates," according to The Athletic's Vic Tafur.
Just suspend, baby.
The Oakland Raiders are about to put Antonio Brown on ice -- after the superstar WR "got into it" with general manager Mike Mayock ... so says ESPN's Adam Schefter.
"The Next Chapter: Antonio Brown and GM Mike Mayock got into it Wednesday, and the team is now planning to suspend its star wide receiver, league sources tell ESPN."
It's obvious what's happening here ... Mayock fined Brown roughly $54,000 for missing team workouts in August.
Brown posted the disciplinary letter from the Raiders on social media and said the team was "hating" on him.
Clearly, Mayock and the Raiders didn't take kindly to the public attack which apparently led to the confrontation between AB and Mayock.
Schefter elaborated ... "Antonio Brown posted the fine letter on social media that Raiders’ GM Mike Mayock sent him. It led to an exchange, which is now leading to further discipline. This is not going away anytime soon."
Mayock had expressed displeasure with Brown for missing practices while dealing with his helmet issue -- after the league told AB he couldn't use his old helmet because it didn't pass the NFL's safety protocol.
