Rudy Gobert has apologized for demonstrating a flippant attitude toward the coronavirus just days before testing positive for COVID-19 himself.

Footage of a Monday press conference showed Gobert, an All-Star player for the NBAs Utah Jazz, touching journalists microphones and recorders in arguing that the public was overreacting to the illness threat.

On Wednesday, however, Gobert tested positive for coronavirus shortly before a game with the Oklahoma City Thunder was set to begin. The game was immediately postponed.

Assuring fans he was under great care, Gobert issued a lengthy apology on Instagram Thursday, noting he had no idea he was infected at the time of the press conference incident.

I was careless and make no excuse, Gobert wrote . 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 as way to educate others and prevent the spread of this virus.
