Teammate Donovan Mitchell was infected by Gobert, who was seen recently ridiculing social distancing measures taken to protect infection during an interview.
The Utah Jazz star said: “The first and most important thing is I would like to publicly apologize to the people I may have endangered.
“At the time I had no idea I was infected. I was careless and make no excuse. I hope my story serves as a warning and causes everyone to take this seriously.
“I will do whatever I can to support using my experience to educate others and prevent the spread of the virus.
