Golf superstar Rory McIlroy will not be heading to Rio.
The No. 3-ranked golfer in the world said concerns about the Zika virus have prompted him to withdraw his name from consideration for the Summer Olympics.
"My health and my family's health comes before anything else," McIlroy said in a statement Wednesday. "Even though the risk of infection from the Zika virus is considered low, it is a risk nonetheless and a risk I am unwilling to take."

The move marks a rapid about-face for the Northern Irish athlete, who earlier in June said initial concerns about the virus had eased.
"Even if I do contract Zika, it's not the end of the world," McIlroy told a June 1 press conference.

Ireland's Olympic Council said it was "extremely disappointed" that McIlroy would not be traveling to Brazil, adding that it has "total confidence" the Games would be "safe for all athletes."
"However, as we have always said, it is down to the individual and of course we respect his decision, which he has taken for personal reasons," it said in a statement.
In addition to McIlroy, a handful of other athletes have said they will skip the Olympics due to Zika fears.
Olympic officials have been trying to reassure athletes and travelers that Zika will not pose a big risk to the games in August.
Studies back up the claims that 500,000 athletes and fans scheduled to attend the Olympics will not be at an unusually high risk of infection.
