Through his official Twitter account Nick Kyrgios announced he won´t play his quarterfinals match against Roger Federer due to a food poisoning (´I am praying that it´s nothing more´). ´After a restless night of being sick I have nothing left and to play a great champion like Roger, I need to be at my best to have a chance´, Kyrgios wrote. ´I didn´t take this decision lightly, these are the matches we train for but I am in no fit state to take to the court.

I am sorry for the fans but I put my health first and I hope you understand. I want to wish Roger the best of the luck for the rest of the tournament´. Federer, who beat Rafael Nadal on Wednesday, advances into the semifinals where he will face Jack Sock or Kei Nishikori.
