Chicago Bears head coach Matt Nagy said running back Tarik Cohen regrets filming the team's locker-room celebration on Instagram Live - a move that caught teammate Kyle Long completely nude in front of his locker.
"I think it's unfortunate that that happened," Nagy told reporters Wednesday, according to Jason Lieser of the Chicago Sun-Times. "Tarik feels bad and is apologetic and embarrassed that it happened.
"I think it's something that you need to do is you learn from it. It was a mistake and nothing that is malicious at all. But it was a mistake so let's make sure that that mistake doesn't happen again to all of our players."
The Bears were celebrating their Monday Night Football win over the Washington Redskins when Cohen shared his livestream on Instagram.
By broadcasting the locker room, Cohen broke the NFL's policy that prohibits players from posting messages on social media until the completion of postgame interviews.
The running back isn't the first notable player to attract controversy with Instagram Live over the last few years. In 2017, Antonio Brown's live feed caught Pittsburgh Steelers head coach Mike Tomlin referring to the New England Patriots as "assholes."
