McIlroy's Olympics bid at risk over Zika
Rory McIlroy says he will pull out of the Olympics in Brazil if the spread of the Zika virus intensifies.
The golfer, who is one of the world's biggest sports stars, is worried the virus may pose a threat to his and his fiancée's plans to have children.
The virus is linked to brain deformities in newborn babies.
The stance of such a high-profile sportperson will cast a doubt over the participation of many top athletes in the Rio 2016 games.
Zika is spread by a mosquito, which is prevalent in the coastal city, and particularly so at the course built in a nature reserve
McIlroy said: "There's going to be a point in the next couple of years where we're (with fiancée Erica Stoll) going to have to think about starting a family.
"Right now, I'm ready to go; but I don't want anything to affect that."
