Dylan Frittelli has become the latest player to withdraw from a PGA Tour event after testing positive for coronavirus.
The South African was tested ahead of this week's Rocket Mortgage Classic in Detroit.
In a statement on the PGA Tour's official website, Frittelli said: "I am experiencing no issues and feel great physically and was surprised and disappointed to learn of the positive test today.
"I'm thankful for the WHOOP strap notification of a minor increase in my respiratory rate overnight.
"However, I'm most thankful for the tour's assistance, procedures and protocols, which I will continue to follow during my self-isolation, so as to keep everyone safe.
"I look forward to getting back on tour once it's safe to do so."
Nick Watney was the first player to test positive for Covid-19 following his opening round at the RBC Heritage earlier this month before several players pulled out of last week's Travelers Championship.
Cameron Champ and Denny McCarthy, who hit an opening round of 67, withdrew from the event following positive results, while Graeme McDowell and Brooks Koepka did not participate after their respective caddies returned positive tests.
Koepka's brother Chase and Webb Simpson withdrew having been in close proximity with a person who had subsequently tested positive, while Bud Cauley, who played with McCarthy but tested negative, pulled out as a precautionary measure.
