Olympic champion Andy Murray has said he will seek medical advice on the Zika virus before confirming his participation in the Rio Games.

Victory over Roger Federer in the men's singles final at London 2012 represents one of the highlights of Murray's illustrious career and the Briton intends to defend his title in Brazil.

However, amid continued concern over the potential risk posed by Zika - a mosquito-borne virus linked to birth defects - Murray is not willing to make a definitive decision just yet.

"I will speak to a couple of doctors about it and see what their advice is," the world number two told BBC Radio 5 live.

"I plan on playing for sure but don't know the exact situation there now. I need to get a little bit more information first before making a decision."

The World Health Organisation (WHO) released a statement on Saturday, which insisted: "There is no public health justification for postponing or cancelling the Games."

That came after the WHO had received an open letter, signed by more than 100 health experts, urging the global body to "reconsider its advice".
