Stan Wawrinka pulls out of Rio Games due to injury

Switzerland's world number four Stan Wawrinka has pulled out the tennis competition at the Rio Olympics because of injury, he said in a statement to the Swiss Tennis Federation on Tuesday.

"I am very sad because after Beijing and London I would have liked to experience my third Olympic Games in Brazil; unfortunately that will now not be possible," he said.

Roger Federer had already announced his decision to skip the whole season in a bid to get ready for the next year.
