American cyclist Tejay van Garderen says he will not compete in Rio this summer due to concerns over the Zika outbreak. The virus is linked to birth defects and the 27-year-old’s wife is currently pregnant.

In a statement through USA Cycling, Van Garderen said that his family was his first priority and he didn’t want to take any risks.

“Although the risks associated with the Zika virus can be minimal and precautions can be taken, my wife Jessica is pregnant, and I don’t want to risk bringing anything back that could potentially have an effect. If circumstances were different I would have loved to be selected again to represent the USA but my family takes priority and it’s a decision that I’m completely comfortable with. I hope I’ll be in the position to race at the 2020 Olympic Games.”

USA Cycling is yet to announce its men’s squad for the Olympics but confirmed to the BBC that Van Garderen had withdrawn from consideration.

Golfers Vijay Singh and Marc Leishman have also said they will not be competing in Rio due to Zika concerns. More than a hundred medical experts signed an open letter saying it would be unethical for the games to go ahead as planned because of the risk to global public health. The World Health Organisation has however dismissed this, saying such a move would “not significantly alter” the spread of the virus.
