Denny McCarthy has become the third PGA Tour player to test positive for coronavirus, and as a result was forced to withdraw from the Travelers Championship on Friday.
Nick Watney first tested positive for COVID-19 at last week's RBC Heritage, before Cameron Champ also tested positive earlier this week. The trio must now all self-isolate for a period of 10 to 14 days.
As a result of McCarthy testing positive, Bud Cauley, who tested negative, decided to withdraw from the tournament due to having played alongside him on Thursday. Matt Wallace, who tested negative, has decided to continue playing the second round, despite having played with McCarthy on day one.
Graeme McDowell and Brooks Koepka both withdrew prior to the start of the tournament earlier this week due to their caddies Ken Comboy and Ricky Elliot testing positive for coronavirus. Webb Simpson also withdrew from this week's event due to a family member testing positive for the virus.
McCarthy issued a statement to Golf Channel that he woke up in the middle of the night feeling "sore and achy."
"I was feeling pretty tired and sore after the round yesterday but didn’t think much of it because I had practiced a lot Monday to Wednesday," said McCarthy.
"Then I woke up in the middle of the night feeling more sore and achy and sensed something was off. I felt like the only thing to do was get tested at that point before I went to the course."
McCarthy had got off to a solid start with a 3-under 67, but under PGA Tour stipulations he must withdraw from the event.
"All of us have an extraordinary responsibility to follow those protocols," said PGA Tour commisioner Jay Monahan.
"For any individual who doesn’t, there will be serious repercussions."
