Two top-10 tennis players have withdrawn from the Rio Olympics, citing concerns about the Zika virus.

Fifth-ranked Simona Halep on the women's side and No. 7 Milos Raonic for the men announced their decisions Friday after their names were listed on the International Tennis Federation's roster for next month's Summer Games.

The 24-year-old Halep posted on Facebook: "Family is much too important for me and I can't risk not being able to have one of my own after my career in tennis is over."

The Romanian was the runner-up at the 2014 French Open.

Raonic made his first major final at Wimbledon this month. In a statement, the 25-year-old Canadian said that "I am making this decision for a variety of health concerns including the uncertainty around the Zika virus."
