Novak Djokovic, the men's world number one tennis player, has tested positive for COVID-19, the Serbian said in a statement on Tuesday, foreign media reported.
Croatia's Borna Coric, Grigor Dimitrov of Bulgaria and Viktor Troicki have previously tested positive after playing in Djokovic's Adria Tour exhibition tournament in the Balkan region.
"The moment we arrived in Belgrade we went to be tested," the 33-year-old said in a statement, adding that he was not showing any symptoms. "My result is positive, just as Jelena's (wife), while the results of our children are negative.
"I am extremely sorry for each individual case of infection. I hope that it will not complicate anyone's health situation and that everyone will be fine. I will remain in self-isolation for the next 14 days, and repeat the test in five days."
