Belgrade, Jun 24 (IANS): Denver Nuggets' star Nikola Jokic has been reportedly diagnosed with COVID-19 which has put on hold his return to the USA from Serbia. Serbian Jokic tested positive for the deadly virus last week and has been asymptomatic.

According to the ESPN report, Jokic had spent time with World No.1 tennis player Novak Djokovic at the Adria Tour earlier this month.

Djokovic, on Tuesday, had announced that he and his wife had contracted the virus following the exhibition event in Belgrade.

This news came after three other players -- Grigor Dimitrov, Borna Coric and Viktor Troicki who participated in the event -- had been diagnosed with COVID-19.

"I am so deeply sorry our tournament has caused harm. Everything the organisers and I did the past month, we did with a pure heart and sincere intentions," Djokovic said in a statement on his official Twitter handle.

"We believed the tournament met all health protocols and the health of our region seemed in good condition to finally unite people for philanthropic reasons. We were wrong and it was too soon.

"I can't express enough how sorry I am for this and every case of infection," he added.

Following the news that Djokovic and his wife have contracted the virus, the remainder of the tournament was cancelled.

"If you attended the Adria Tour or were around any attendees please get tested and practice social distancing. For those in Belgrade and Zadar, we will be sharing health resources in the immediate future.

"The rest of the tournament has been cancelled and we will remain focussed on all those who have been affected. I pray for everyone's full recovery," the Serbian said.
