The 22-year-old took to his official Twitter handle and informed that he has withdrawn from this weekend's All-American Team Cup special event in Atlanta after being diagnosed with COVID-19.

Tiafoe also revealed that he has been training in Florida over the past two months and tested negative for the virus as recently as last week.

The tennis player added that he has now quarantined himself as advised by the medical staff and will undergo second COVID-19 test next week.

"I am scheduled to have a second test early next week, but have already begun the quarantine protocol as advised by the medical staff here in Atlanta. While I’ve been so excited to get back out there, the health and safety of everyone continues to be a top priority," he further tweeted.
