(CNN)A third PGA golfer has tested positive for coronavirus since golf resumed on June 11.
Denny McCarthy withdrew from the Travelers Championship after testing positive for coronavirus, the PGA Tour said in a statement on Friday.
"For the health and well-being of all associated with the tournament and those within the community, the Tour is implementing its response plan in consultation with medical experts, including working with those who may have had close contact with him," the statement said.
McCarthy said he felt tired on Thursday, but thought it was because of how hard he practiced earlier in the week.
"Last night I woke up in the middle of the night with additional aches and soreness and sensed something was off," McCarthy said. "I felt like the only thing to do was get tested at that point before I went to the course."
The PGA said McCarthy will self-isolate and follow guidelines set by the Centers for Disease Control and Prevention.
