Cooper was caught on video at a Kenny Chesney concert, saying "I will fight every (expletive) here."
Cooper was fined by the team for the comments.
"Obviously, I was very embarrassed. I'm still embarrassed about the situation," Cooper said, via NFL.com. "Words hurt, and I'm crushed by it. But it felt good to know my teammates were supporting me."
