The Adria Tour has been a great tournament during the ATP Tour suspension. All went great and there were no major problems with the safety of fans or players. Everything until players met in Zadar. First, Grigor Dimitrov was tested positive for the COVID-19 and due to that, the Grand Finale in Zadar was canceled.

Following Dimitrov's positive test, all of the people that were in contact with the Bulgarian were tested for the COVID-19, including Borna Coric. Now, the young Croatian revealed that he was tested positive for the COVID-19. On social media, he wrote:

"Hi everyone, I wanted to inform you all that I tested positive for COVID-19. I want to make sure anyone who has been in contact with me during the last few days gets tested! I am really sorry for any harm I might have caused! I'm feeling well and don't have any symptoms. Please stay safe and healthy! Lots of love to all!"
