Things are getting ugly in Pittsburgh.

The Steelers are already without star running back Le’Veon Bell, who surprised many people by not ending his contract holdout when the regular season started. Then members of the offensive line took repeated jabs at Bell in the media. Then the team only managed a tie against the Cleveland Browns in Week 1. And the story of Week 2 was wide receiver Antonio Brown barking at his coaches over a perceived lack of usage. Oh, and they lost 42-37 to the Kansas City Chiefs.

The newest headache appears to be that Brown didn’t bother to show up for work on Monday. According to the Pittsburgh Post-Gazette, Brown was not present at the Steelers’ training facility on Monday for meetings and film review. It was only a day earlier that Brown rushed out of the locker room and refused to speak to media after the loss to the Chiefs.

Brown is clearly frustrated. He tweeted a thinly veiled trade request on Monday morning when a former Steelers employee suggested he wouldn’t be nearly as good without quarterback Ben Roethlisberger throwing him the ball.

Players have an off-day on Tuesday, so we may not know more about Brown’s intentions until Wednesday. Between his sideline antics, cryptic tweets, and now skipping a day of work, it appears the Steelers have an issue on their hands. Last month Brown tweeted out a threat to punch a journalist who had dared to criticize him in a story — a tweet he later deleted.
