Australian golfer Adam Scott has tested positive to coronavirus in the US, the PGA Tour has confirmed.

The tour says the world number 15 will have its 'full support throughout his self-isolation period under CDC guidelines'.

Scott, 40, will now self-isolate for 10 days and has withdrawn from the Zozo Championship in California, where he was expected to be among the biggest names to compete at the tournament.

'While it's difficult news to receive - as I really looked forward to playing this week - my focus now is on recovery for the final stretch of the fall,' Scott said.

The 2013 Masters winner is the 15th player to test positive since the PGA Tour resumed in June after it was shutdown by COVID-19.

World number one Dustin Johnson tested positive last week as did world number 17 Tony Finau several weeks ago.

The winner of 14 PGA Tour titles, Scott spent time back home in Australia during the height of the pandemic and was one of the last players to rejoin the tour after it resumed in June.

Scott has competed in just four tournaments since, including the US Open in September. 

First alternate Jim Herman will replace Scott in the field at the Zozo Championships, which was relocated from Japan to Thousand Oaks, California due to COVID-19.
