6:00 AM PT -- 6/23 Djokovic now says he's COVID-19 positive as well ... and he's issuing a mea culpa for all of his actions this past month that helped lead to an outbreak of coronavirus in the tennis community.
"We organized the tournament at the moment when the virus has weakened, believing that the conditions for hosting the Tour had been met," Djokovic said, adding his wife also tested positive for the virus.
"Unfortunately, this virus is still present, and it is a new reality that we are still learning to cope and live with."
Djokovic continued, "I am extremely sorry for each individual case of infection. I hope that it will not complicate anyone's health situation and that everyone will be fine."
The world's No. 1-ranked tennis player -- who says he is NOT displaying any symptoms -- added he'll now begin a 14-day quarantine.
Novak Djokovicis under fire for partying topless just days before his tennis tourney had a small coronavirus outbreak ... with one of Joker's peers calling the whole thing a "poor example."
Here's the deal ... the world's #1 ranked tennis player hosted a tournament in Croatia over the weekend but it was canceled before the final match because two of the tournament's stars contracted COVID-19.
As it turns out, one of the two guys who tested positive -- Grigor Dimitrov -- had been partying with Djokovic and several other famous tennis players at a Croatian hot spot just days before.
