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.
