Last week, Brown didn’t play during the Steelers’ final game after he reportedly got into a dispute with quarterback Ben Roethlisberger.
Clark, meanwhile, criticized Brown for his me-first attitude, saying that Brown went on social media when coach Mike Tomlin was speaking to the team.
He continued: “Obviously you want to get something for him. He’s one of the best wide receivers in the league. As a matter of fact, he’s one of the best football players in the league.”
On social media, according to an NFL reporter, Brown responded with “Uncle Tom,” a derogatory term used to described a black person eager to win the approval of white people.
Brown and Clark were Pittsburgh teammates from 2010 to 2013.
He added: “The rest is just the rest....... I’ll let that be. No one wins here publicity. Let’s all keep the same energy all the time. Happy New Year.”
But the Steelers missed the playoffs after losing four of their last six games.
In the Post-Gazette report, Brown showed up at Heinz Field in Pittsburgh in the hopes he'd play against the Cincinnati Bengals for the final game following the football-throwing incident. Some players were surprised by the move, saying it was “embarrassing” for the team and “the worst I’ve seen.”
Tomlin said after practice that Brown was dealing with a knee issue.
Earlier this year, Brown berated two members of the media. In April, he was also accused of throwing furniture from the 14th floor of a Florida luxury apartment complex. He was reportedly angry about $80,000 that went missing as well as a gun, the Gazette noted.
Clark, 39, played safety for the Steelers, Washington Redskins, and New York Giants for 11 seasons before retiring in 2014. In 2015, he was signed by the ESPN as an NFL analyst.
