Djokovic tests positive for COVID-19 after Adria Tour involvement

Novak Djokovic is the latest tennis player to test positive for COVID-19 after organizing and taking part in the Adria Tour.

The heavily criticized exhibition series featured full crowds in Serbia and Croatia and did not implement any physical distancing protocols.

The world No. 1, who has defended staging the tournament amid a pandemic, is the fourth tennis player to contract the disease, following similar results for Grigor Dimitrov, Borna Coric, and Viktor Troicki in recent days.

Djokovic said his wife, Jelena, also tested positive upon their return to Belgrade.

"Everything we did in the past month, we did with a pure heart and sincere intentions," Djokovic said in a statement. "Our tournament meant to unite and share a message of solidarity and compassion throughout the region."

He added: "It was all born with a philanthropic idea, to direct all raised funds toward people in need, and it warmed my heart to see how everybody strongly responded to this. We organized the tournament at the moment when the virus has weakened, believing that the conditions for hosting the Tour had been met."

The 33-year-old, who has previously said he would be against taking a vaccine for the virus if it was made mandatory for travel, has been widely criticized for his involvement in the series.

"Boneheaded decision to go ahead with the 'exhibition,'" Nick Kyrgios tweeted on Monday after Dimitrov and Coric revealed their positive tests. "Speedy recovery fellas, but that's what happens when you disregard all protocols. This is not a joke."

Kyrgios also called out Djokovic after videos began circulating on social media showing the Serbian partying with other players and coaches as part of the Adria Tour event:

Djokovic said he'll self-isolate for 14 days and apologized to anyone who contracted the disease as a result of the tournament.
