Grigor Dimitrov said on Sunday said he has tested positive for COVID-19, making him the highest-profile tennis player to reveal he has the disease.
The 29-year-old Bulgarian had been competing in the Adria Tour exhibition tournament in Croatia until he withdrew due to feeling ill during the weekend.
The final of the Croatia event in the coastal resort of Zadar, the second leg of the tour which would have featured world number one Novak Djokovic and Russian Andrey Rublev, was cancelled as a result.
“I want to reach out and let my fans and friends know that I tested positive back in Monaco for COVID-19,” former world number three Dimitrov wrote on Instagram.
“I want to make sure anyone who has been in contact with me during these past days gets tested and takes the necessary precautions.
“I am so sorry for any harm I might have caused. I am back home now and recovering. Thanks for your support and please stay safe and healthy.”
Goran Ivanisevic, the director of the tour’s Zadar leg and Djokovic’s coach, was greeted with jeers from the fans when he broke the news courtside.
“We have just been informed that Grigor Dimitrov has tested positive for coronavirus and we will have to call off the final of the tournament in Zadar,” he said.
“Unfortunately we had to make the decision as we don’t want anybody else to catch the virus.”
Dimitrov pulled out of the tournament on Saturday after he felt unwell following his opening singles match against Croatian Borna Coric.
