Rio 2016: Branden Grace is the latest golfer to pull out of Olympics
South Africa's Branden Grace has pulled out of this summer's Olympics in Rio because of fears around the Zika virus.
Grace, 28, who won the RBC Heritage in April, said: "I am getting married in November and hoping to start a family. I must put their health first.
"I really hope to be able to qualify again in four years' time."
Fiji's Vijay Singh and Marc Leishman of Australia have already said they will not play because of the virus and the absence of the top players is a blow as the sport returns to the Olympics for the first time since 1904.
Zika, a mosquito-borne virus, has been linked to brain defects in newborn babies.
