Kyrgios pulls out of Federer match at Indian Wells

Nick Kyrgios has been forced to withdraw from his quarter-final against Roger Federer at the Indian Wells Masters with a suspected bout of food poisoning.

The Australian confirmed the news on Friday in a statement posted to social media:

"Unfortunately I am unable to play today due to sickness," Kyrgios wrote. "At this stage we think it's food poisoning, and I'm praying 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. 

"I don't take this decision lightly, these are the matches we train for but I'm in no fit state to take the court.

"I'm sorry to the fans but I have to put my health first and I hope you understand.

"I want to wish Roger the best of luck for the rest of the tournament and thank every one for their support so far her at the BNP Paribas Open. I will definitely be back. Thank you."

Kyrgios advanced to the quarter-finals at Indian Wells on Wednesday with a superb win over Novak Djokovic, and many were anxiously awaiting the contest with Federer.

As for the Swiss ace, he is automatically through to the semi-final, where he will face the winner of the match between Japan's Kei Nishikori and American Jack Sock.
