The Baltimore Ravens have confirmed the release of Earl Thomas after an altercation with Chuck Clark in practice.
Seven-time Pro Bowler Thomas clashed with his team-mate during training camp on Friday, with reports alleging a punch was thrown at his fellow safety.
And on Sunday the Ravens announced they had taken decisive action against the 31-year-old.
"We have terminated Earl Thomas' contract for personal conduct that adversely affected the Baltimore Ravens," the team said in a statement.
Posting to his Instagram story shortly after the news was confirmed, Thomas wrote: "Appreciate the Ravens organization for the opportunity.
"Had a great run ... Wish things would have ended different but you live and you learn.
"Thank you [Ravens GM] Eric DeCosta and everyone else who played a role in bringing him to B-More. Wish you guys the best."
Thomas signed a four-year deal in the previous offseason and was voted to the Pro Bowl after starting 15 games, in which he made 47 tackles and had two interceptions, helping the Ravens to a 14-2 regular season record.
