Wimbledon runner-up Milos Raonic has pulled out of this summer's Olympic Games due to "health concerns".
The 25-year-old, who was beaten by Andy Murray in the final at SW19 last weekend, is currently ranked seventh in the world.
A number of high-profile golfers, including the world's top four of Jason Day, Jordan Spieth, Dustin Johnson and Rory McIlroy, have also pulled out of the Games in Rio, and Raonic admitted that the Zika virus was part of the reason behind his decision.
"It is with a heavy heart that I am announcing my withdrawal from participation in the Rio 2016 Olympic Games," he wrote in a Facebook post.
"After much deliberation with my family and coaches, I am making this decision for a variety of health concerns including the uncertainty around the Zika virus. This was a difficult, personal choice and I do not wish for it to impact the decision of any other athlete heading to the Games.
"I would like to thank Tennis Canada and the Canadian Olympic Committee for their ongoing support. I am very proud to have competed for Canada at the London 2012 Summer Olympics, and on the world stage at several Davis Cup events. I look forward to cheering on Team Canada this summer."
Veteran Daniel Nestor is now expected to replace Raonic as Vasek Pospisil's doubles partner in Rio.
