Stan Wawrinka has asserted that Nick Kyrgios has not properly apologised for his controversial sledge at last week's Rogers Cup.
Kyrgios has come under heavy criticism for the crude remarks he made about 19-year-old tennis player Donna Vekic, who is reportedly dating Wawrinka.
A courtside microphone caught Kyrgios telling Wawrinka that: "Kokkinakis banged your girlfriend. Sorry to tell you that mate", referring to an apparent past liaison involving Vekic and Kyrgios' compatriot Thanasi Kokkinakis.
Kygrios initially said that he has made the remark because Wawrinka had been "lippy" in their ill-tempted encounter, but later posted an apology on his Facebook page. He has since been fined by the ATP Tour for his remarks.
When asked about the matter following his 3-6, 7-6 (3), 6-3 victory over Borna Coric at the Western & Southern Open, Wawrinka said that he was trying to move on from the incident.
"I'm trying to put it away. But what's happened, people don't see exactly the consequence for everybody. So I'm trying to put it away," he told reporters.
When pressed further about whether he was happy with Kyrgios' apology, Wawrinka responded: "Uh no, he didn't apologise, no. But I prefer not to talk about him. Thank you."
Kyrgios, who was knocked out of the Western & Southern Open on Tuesday by Richard Gasquet, is expected to discover on Thursday if he is to face any further sanctions for his comments.
