Rory McIlroy concerned about Zika virus ahead of Olympics

Rory McIlroy has become the latest, and most high-profile, golfer to express reservations about competing in the Rio Olympics this year due to the ongoing threat of the Zika virus.

The world number three, who clinched his first win of 2016 at the Irish Open over the weekend, is due to participate for Ireland as the sport makes its return to the Games for the first time since 1904.
