World No.1 golfer Dustin Johnson tests positive for Covid-19

Dustin Johnson has tested positive for Covid-19, the PGA Tour said Tuesday, forcing the world number one golfer's withdrawal from the CJ Cup in Las Vegas.

Johnson underwent a test after experiencing symptoms of coronavirus ahead of Thursday's opening round at Shadow Creek, the tour said in a statement.

The 36-year-old, whose last outing came at last month's US Open, is now undergoing self-isolation, the tour added.
