Nick Kyrgios received a fine of $25,000, and was suspended for eight ATP tournament weeks following his conduct at the 2016 Shanghai Masters
Nick Kyrgios has been fined $10,000 (£7,573) for unsportsmanlike conduct after he quit his first-round match at the Shanghai Masters.
Kyrgios was booed as he left the court on Tuesday after he lost the first set on a tie-break against Steve Johnson.
He had earlier received a warning for smashing two balls out of court in frustration at a line call.
The Australian has also not been allowed to collect his $21,085 (£15,967) prize money.
Kyrgios was unable to collect his prize money because he failed to get signed off for a medical afterwards to prove he was unwell or hurt.
The 13th seed had already been given a point penalty for an audible obscenity when he was heard to say he would quit against Johnson if he lost the tie-break.
After his opponent served an ace on his first set point, Kyrgios walked over to shake hands.
Umpire Fergus Murphy asked the Australian if he needed medical help before the player walked off court to boos from spectators.
At the same tournament last year he was fined for his behaviour and banned.
He later posted an apology to fans on social media, saying he had been struggling before the match with a stomach bug.

The incident comes just two days after the temperamental Kyrgios lost to Rafael Nadal in the final of the China Open after becoming frustrated by a line call in the first set.
At last year's Shanghai Masters, Kyrgios argued with the umpire and a spectator during a match with Mischa Zverev. He was fined $16,500 (£13,533) for his behaviour, which included "lack of best efforts", and served a three-week tournament ban.
Meanwhile, British number three Kyle Edmund was beaten by Croatian fourth seed Marin Cilic in the second round in Shanghai.
The 22-year-old, who defeated Jiri Vesely 6-3 6-2 to set up the tie with the 2014 US Open champion, lost 6-3 7-6 (7-5) in one hour 37 minutes.
British number two Aljaz Bedene progressed to round two after beating Italian world number 39 Paolo Lorenzi in straight sets.
The 28-year-old won 6-1 6-4 in 73 minutes and will now face German third seed Alexander Zverev, who was given a first-round bye.
