Novak Djokovic is facing a fine of up to $20,000 (£15,000) after already being docked the $250,000 (£190,000) he earned by reaching the round of 16 at the US Open.
The World No1 was disqualified in his match with Pablo Carreno Busta in shocking fashion as he struck a line judge with the ball while venting his frustration.
Djokovic had just dropped his serve to trail 6-5 in the opening set and the ball he hit cannoned into the throat of the court-side official.
Though he did not mean to hit the line judge and a lengthy discussion with tournament referees followed, the rules on such incidents are clear and Djokovic was disqualified from the tournament.
The Serb collected his possessions and exited the court after accepting the verdict and many expected he would issue an apology in his post-match press conference.
But it was confirmed not long after the disqualification that Djokovic would not be honouring his media obligations – which is set to land him in more hot water.
The fine for skipping his post-match duties could be up to £15,000, while the incident at Flushing Meadows is the latest in a string of controversial actions by Djokovic despite his stellar unbeaten season up to that point.
He has launched a breakaway men’s player union despite strong opposition from other huge names including Roger Federer, Andy Murray and Rafael Nadal.
And the ill-fated Adria Tour Djokovic organised in June ended in an embarrassing abandonment after a number of players – including Grigor Dimitrov and Djokovic himself – tested positive for coronavirus.
In the build up to the positive COVID-19 test, the participants of the tour had been seen flouting social distancing guidelines.
Meanwhile, Djokovic did issue an apology following the incident at the US Open on Sunday despite opting not to fulfil his media duties.
He wrote on social media: “This whole situation has left me really sad and empty. I checked on the lines person and the tournament told me that thank God she is feeling ok.
“I‘m extremely sorry to have caused her such stress. So unintended. So wrong. I’m not disclosing her name to respect her privacy.
“As for the disqualification, I need to go back within and work on my disappointment and turn this all into a lesson for my growth and evolution as a player and human being.
“I apologise to the @usopen tournament and everyone associated for my behavior.
“I’m very grateful to my team and family for being my rock support, and my fans for always being there with me. Thank you and I’m so sorry.”
