The Bulgarian 29-year-old had been competing in the Adria Tour exhibition tournament in Croatia.
Dimitrov also appeared at the Serbian leg of the Adria Tour last week
and has come into contact with top 10 players Novak Djokovic, Alexander
Zverev and Dominic Thiem.
He returned home to Monaco after feeling unwell during his defeat to
Borna Coric yesterday and has since tested positive for Covid-19.
The final of the event, which would have featured world number one Novak Djokovic, 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
