Marshawn Lynch has been fined $50,000 for violating the NFL's media policy.

The NFL will also collect $50,000 on a fine imposed during the 2013 season that was held in abeyance in anticipation of future cooperation.

The NFL media policy mandates that players must be available to the media during the practice week at the team facility and in the locker room following all games. 

Lynch quickly dressed and left the team's locker room after Sunday's loss to the Kansas City Chiefs, calmly walking away when reporters asked to speak to him. Lynch later did a phone interview with one reporter -- NFL.com's Michael Silver -- after leaving the locker room.

According to the media policy, "Star players, or other players with unusually heavy media demands, must be available to the media that regularly cover their teams at least once during the practice week in addition to their required postgame media availability."

"I thought I covered my bases by doing an interview after the game -- what I was told to do. If it wasn't good enough, then I don't know what to say," Lynch told ESPN's Josina Anderson after receiving news of the fine. "That's it. Now I understand it wasn't good enough for the league, or for whoever is fining me."

Lynch will appeal the fine.
