World No1 golfer Dustin Johnson has tested positive for Covid-19, forcing him to pull out of his week's CJ Cup.
The American notified PGA Tour officials he was experiencing symptoms and after undergoing a test, returned a positive result.
Johnson told the tour's website: "Obviously, I am very disappointed. I was really looking forward to competing this week, but will do everything I can to return as quickly as possible.
"I have already had a few calls with the tour's medical team and appreciate all the support and guidance they have given me."
Earlier, South African Jbe Kruger was withdrawn by the European Tour from this week's Scottish Championship after testing positive for the virus.
Kruger, who is asymptomatic, was tested upon his arrival at Fairmont St Andrews on Monday as part of the pre-tournament screening process and will now remain in self-isolation for a minimum of 10 days in accordance with mandatory Public Health Scotland and NHS Fife guidelines.
No other contacts were identified as part of the track and trace process other than Kruger's wife - and caddie - Denise, who will also be managed in accordance with Public Health guidelines.
