Nick Kyrgios said what?! Aussie slammed, then fined, for lewd sledge

    (CNN)Nick Kyrgios was fined $10,000 by the ATP after sledging Stan Wawrinka at the Rogers Cup in Montreal and more action may yet be taken against the controversial Australian.

    Microphones courtside picked up Kyrgios' lewd comment -- he linked the Swiss' apparent girlfriend to men's pro Thanasi Kokkinakis -- on Wednesday although the two-time grand slam champion didn't appear to hear it at the time.
      Such behavior might be commonplace in other sports but is extremely rare in tennis.
      The ATP earlier Thursday said that the 20-year-old had been fined for what it called an "insulting remark" during the second round contest and disclosed the amount several hours later, after Kyrgios was notified. The $10,000 sum is the maximum financial penalty allowed on site, according to the ATP.
      The men's governing body, though, "is still reviewing" the incident "and additional penalties may be forthcoming," an ATP spokesman said in an email sent to CNN.com.
      It's not the first time Kyrgios has been sanctioned financially: He was forced to relinquish $9,500 at Wimbledon for unsportsmanlike conduct and uttering an audible obscenity.
      Kyrgios, who has pocketed about $790,000 in prize money in 2015, issued an apology on his Facebook page.
      "I would like to take this opportunity to apologize for the comments I made during the match last night vs Stan Wawrinka," said Kyrgios. "My comments were made in the heat of the moment and were unacceptable on many levels.
      "In addition to the private apology I've made, I would like to make a public apology as well. I take full responsibility for my actions and regret what happened."
      A livid Wawrinka -- who divorced wife Ilham earlier this year -- had called on the ATP to penalize the world No. 41 and said he confronted Kyrgios in the locker room.
      "It's not the first time that he has big problems on the court in terms of what he says and in terms of how he acts," Wawrinka, who retired in the third set with a back injury, told reporters in French in a video that was posted online and translated by tennis blogger Stephanie Myles.
      "I just hope that the ATP will take big measures against him because he's young, maybe -- but there's no excuse. Every match he has problems. Every match he behaves very badly.
      "On top of that, he doesn't just behave badly towards himself. He behaves very badly towards the people around -- the other players, the ball kids, the umpires."
      Wawrinka's coach, Magnus Norman -- known for being mild mannered -- ripped Kyrgios on Twitter.
      What happened in the locker room post match "will stay in the locker room but I think there are things, regardless of how you are, regardless of the stress you have on court, there are things you just can't say," said Wawrinka.
      Kyrgios suggested his barb came after he was provoked by Wawrinka.
      "He was getting a bit lippy at me," Kyrgios said in a television interview after the match.
      "I definitely felt there was a bit of tension out there tonight," he told reporters Wednesday.
      That may have stemmed from when the two played at the Aegon Championships in London in June.
      After Wawrinka progressed in straight sets, Kyrgios said he felt ill.
      Cue this reply from Wawrinka: "When I read before the match, he was ready, excited for the challenge. And now he was sick. I think he's saying a lot of things every day, so it's quite interesting for journalists to hear that."
