The total financial penalty for Novak Djokovic's US Open disqualification: $267,500.

Djokovic has been docked an additional $7,500 for skipping the mandatory postmatch news conference after being defaulted in the fourth round at Flushing Meadows for accidentally hitting a line judge in the throat with a ball after dropping a game.

The maximum fine for that infraction is listed as $20,000 in the Grand Slam rulebook.

That also is the most someone can be fined for unsportsmanlike conduct; Djokovic earlier was told to pay $10,000 for that violation.

Those two fines are in addition to losing his $250,000 in prize money for making it to the fourth round at the US Open.

To put the money in context: Djokovic has earned more than $140 million in prize money over his career, aside from millions more in endorsement deals.
