Nick Kyrgios says he is unable to speak about assault allegation

On the eve of his quarter-final match against Chile's Cristian Garin, local police confirmed the 27-year-old Australian was to appear in a Canberra court next month. Australian media said the charge was related to a complaint made by Kyrgios's former partner Chiara Passari.

The controversial Kyrgios made headlines for the right reasons on Wednesday when he beat Garin in three sets, but afterwards he was asked about the allegations. "Obviously I have a lot of thoughts, a lot of things I want to say, kind of my side about it," he said.

"I've been advised by my lawyers that I'm unable to say anything at this time. "Look, I understand everyone wants to kind of ask about it and all that, but I can't give you too much on that right now." He did say, however, that it had been hard to read the stories in the build-up to his match, but that he had not let them affect his performance on the court.
