The NFL has fined Lynch $50,000 for leaving the locker room without speaking to reporters following Sunday's 24-20 loss to the Kansas City Chiefs.
The 28-year-old, who has been linked with a move away from the 2014 Super Bowl champions at the end of the season, will also be docked an additional $50,000 for a fine that was imposed last year for failing to fulfil his media commitments but held in abeyance in anticipation of future cooperation.
"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.
"That's it. Now I understand it wasn't good enough for the league, or for whoever is fining me."
Lynch has rushed 813 yards and nine touchdowns this season for the Seahawks, who are 6-4 in the National Football Conference (NFC) Western Division.
