Cancelling this summer's Olympic Games in Rio because of concerns over the Zika virus would be "unthinkable", says Novak Djokovic.
The world number one hopes to compete for Serbia in Brazil.
Djokovic, 29, said: "For the moment I'm planning to play. Nothing is changing. But let's see what happens."
The World Health Organisation (WHO) has played down fears over the spread of the virus, which is linked to severe birth defects.
Senior WHO official Bruce Aylward told the BBC risk assessment plans were in place, and reiterated there was no need to delay the Games, which are scheduled to take place in Rio de Janeiro from 5-21 August.
