It started as a joke: Before leaving a post-practice interview session Rudy Gobert touched all the tape recorders that were placed before him on a table, devices that reporters who cover the Utah Jazz were using during an availability with him on Monday before a game with the Detroit Pistons.

It isn’t so funny now — not with two Jazz players now having tested positive for the virus, and with a league on edge.

Gobert is now the NBA’s Patient Zero for coronavirus after becoming the first player in the league to test positive, a person with knowledge of the situation told The Associated Press. And a second person with knowledge told AP on Thursday that Gobert’s Utah teammate, Donovan Mitchell, tested positive as well.

“As a follow-up to yesterday’s positive COVID-19 test, Oklahoma health officials tested all members of the Utah Jazz traveling party, confirming one additional positive outcome for a Jazz player,” the Jazz said in a statement Thursday. “We are working closely with the CDC, Oklahoma and Utah state officials, and the NBA to monitor their health and determine the best path moving forward.”

The Jazz have not confirmed that Gobert and Mitchell are the two positive tests.

Gobert, the 7-foot-1 Frenchman, is at the center of why the league has been shut down for the foreseeable future:

— Utah’s game against Oklahoma City Wednesday night was canceled and the Pistons are among five teams that have played the Jazz — and Gobert — since the start of March, the others being Boston, Toronto, New York and Cleveland. And Washington, which played Utah in late February, said Thursday that it was having its players, coaches and basketball operations personnel self-quarantine for the next three to four days.

The Wizards played at Utah on Feb. 29. Washington also played Tuesday against the New York Knicks, another recent opponent of the Jazz. The Wizards said players, coaches and basketball operations staff who have flu-like symptoms will be tested for coronavirus.

— The Raptors also said Thursday they are self-quarantining. “Our players, coaches and traveling staff have all been advised to into self-isolation for 14 days,” the team said, also confirming that Toronto players had been tested.

— Gobert shared the court with 50 opposing players in those games, plus 15 referees.

— One of the refs was Courtney Kirkland, who was to work th e New Orleans-Sacramento game on Wednesday that got canceled because he had been on the court with Gobert two nights earlier, and who knows how many ballboys, stat-crew employees, security guards, attendants and others did as well.

— Then there’s Gobert’s own teammates and the Jazz coaches and staff. And everyone he’s been on a plane with in recent days. Or shared a hotel elevator with. Or dined with. Or shook hands with. And so on, and so on.

“I’m sure I probably had contact with him,” Detroit’s Langston Galloway said.

He added, “Staying focused on that moment of interaction with a lot of different people and knowing that at the end of the day you might have touched the ball, you might have interacted with a fan and just being (cautious) with that going forward.”

The NBA shutdown could cost teams well into the hundreds of millions of dollars depending on how long the shutdown lasts. Those teams that have faced Gobert in recent days will likely face some testing. And some of those Jazz reporters said they were getting tested for COVID-19, just in case.

“It’s unprecedented,” Detroit Pistons coach Dwane Casey said. “I think it’s the prudent thing to do. And what went on in Utah, I don’t know all the information but that just shows you how fragile everything is right now.”

This is the reality of the coronavirus, which was labeled a pandemic by the World Health Organization on Wednesday weeks after beginning its havoc-wreaking global run that has sickened well over 100,000 and killed more than 4,000.

For most people, the new coronavirus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia.

The vast majority of people recover from the new virus. According to the WHO, people with mild illness recover in about two weeks, while those with more severe illness may take three to six weeks to recover.

Charlotte coach James Borrego said these are scary times in the NBA, and no one argued.

“They’re all concerned and rightfully so,” Casey said. “Everybody in our league should be concerned. I think everybody in our country right now, more than just basketball, is concerned. We all have to take care of ourselves and look out for our fellow man.”

That’s what Orlando’s Evan Fournier did Wednesday night.

Fournier, a French national teammate of Gobert’s, reached out to him after news of the diagnosis and leaguewide shutdown broke.

“Was just on the phone with Rudy,” Fournier wrote. “He is doing good man. Lets not (panic) everyone. Love you all.”
