A visitor to Massachusetts' newest resort casino tested positive for coronavirus, officials said Thursday evening.

The patient visited Encore Boston Harbor on March 5, the Massachusetts Gaming Commission said in a statement.

The Boston Globe reports that the individual who went to the casino is Utah Jazz star Donovan Mitchell, who confirmed earlier Thursday that he tested positive for COVID-19. He was in town March 5 for the Jazz's game against the Celtics the following night.

According to the commission, the person was not exhibiting symptoms at the time, and the Department of Public Health said the risk of exposure is minimal.

"DPH recommends that Encore continue its enhanced sanitation practices," the commission said in its statement. "Additionally, Encorehas reported that, out of an abundance of caution, all identified individuals have agreed to self-quarantine measures."
