Nick Kyrgios has been fined over quitting in a first-round tie at the Shanghai Masters.
The Australian has been ordered to pay $10,000 (£7,573) for unsportsmanlike conduct.
Kyrgios, 22, was booed as he left the court on Tuesday, 10 October, after he lost the first set on a tie-break against Steve Johnson, having earlier received a warning for smashing two balls out of court in frustration at a line call.
The 13th seed has also not been allowed to collect his $21,085 (£15,967) prize money.
He later posted a message on social media, saying he had been suffering from a stomach bug and hurt his shoulder before the match.
