Belgian sailor ill after race on Rio bay

Evi van Acker of Belgium has reported feeling ill after competing in the Laser Radial class on polluted Guanabara Bay, sailing's governing body says.

World Sailing spokesman Darryl Seibel says van Acker, the bronze medallist at London, was evaluated by the chief medical officer after her races on Wednesday, and then evaluated further by medical officials from the Belgian team that night.

It's not immediately clear whether the illness is because of the polluted water.

Seibel said om Thursday that this appears to be an isolated case and van Acker is the only sailor who has reported feeling ill in the opening days of the regatta.

Van Acker, a favourite to return to the podium in Rio, has had consistently worse performances. She was second and 12th on Monday, second and 29th Tuesday and then 16th and 15th in tough conditions on Wednesday.
