Zika strikes again. More and more athletes are dropping like flies from the Rio Olympics that are set to start in less than a week.

American tennis brothers Bob and Mike Bryan are the latest athletes who have said no to Rio, citing health concerns in their decision to withdraw from the Games.

“After countless hours of deliberation, Mike and I have decided to forego the Rio Olympics,” Bob Bryan wrote Saturday in a statement on Facebook. “Though we’d love to compete again, as husbands and fathers, our family’s health is now our top priority.

The twin brothers are Olympic veterans, having competed in the 2004, 2008 and 2012 Games. They are also the defending gold medalists in the men’s doubles category.

The Bryans aren’t the first Team USA tennis players to announce Rio as a no-go.

Also not attending this year’s Games are men’s singles players John Isner (ranked No. 16) and Sam Querry (ranked No. 29). Both cited other scheduling priorities.

Tennis star Roger Federer also withdrew his participation this past week due to injury.
