Harris English is the fifth player to test positive for COVID-19 since the PGA Tour's return earlier this month.
According to the PGA Tour, English tested positive in the pre-screening process ahead of the Rocket Mortgage Classic and he has withdrawn from the event.
"I feel healthy," English said. "I'm pleased that the new safety protocols we have in place worked this week. I fully support the Tour's new rule of not allowing anyone on the tournament grounds until testing negative, as protecting others in the field and everyone affiliated with the tournament and the community should be the No. 1 priority as a result of a positive test.
"I appreciate the Tour's support and I look forward to competing again after I'm fully recovered."
English did not compete in the Travelers Championship last week and will now be in self-isolation as recommended by the CDC.
Nick Watney, Cameron Champ, Denny McCarthy and Dylan Frittelli round out the five players who have tested positive on the PGA Tour since June 11.
