Three-time champion Michael van Gerwen has withdrawn from the PDC World Darts Championship after testing positive for coronavirus on Tuesday.
The Dutchman's positive test was revealed ahead of his match against Chris Dobey, who receives a bye into the last 16 at Alexandra Palace.
World number three Van Gerwen's compatriots Raymond van Barneveld and Vincent van der Voort also returned positive tests at the tournament in London.
Five-time champion Van Barneveld tested positive following his second-round defeat to 2018 winner Rob Cross.
Van der Voort was unable to play James Wade on Monday after discovering that he had contracted COVID-19.
The PDC stated that the evening session on Tuesday would go ahead, with Cross up against Daryl Gurney and 2020 champion Peter Wright meeting Damon Heta.
