Losing with dignity simply shouldn't involve a one-finger salute.

The NBA announced on Saturday that Atlanta Hawks forward Ivan Johnson has been fined $25,000 for "directing an obscene gesture toward fans" after a Game 6 loss to the Boston Celtics on Thursday night.

Johnson was caught putting his left middle finger in the face of a fan wearing a Celtics jersey as he left the court following Boston's series-clinching victory. This image shows Johnson's obscene act.

It was an unsurprising end to the volatile 28-year-old rookie's first season in the NBA as Johnson was banned from the Korean Basketball League for making an obscene gesture towards a referee.

Johnson averaged 6.4 points and 4.0 rebounds in 16.7 minutes per game for the Hawks this season.
