It was not immediately clear if there was more than one positive test on the Bucks, but Milwaukee plans to keep its facility closed for workouts until the team's traveling party departs Thursday for the league's restart in Orlando, Florida, sources said.
One member of Sacramento's traveling party tested positive for COVID-19, a source told ESPN's The Undefeated, and the Kings also plan to keep their practice facility closed through their departure for Orlando on Wednesday.
Per the league's health and safety guidelines, any player who contracts the coronavirus must quarantine and test negative twice before being medically cleared to make the trip to Orlando.
The Bucks have the NBA's best record at 53-12 heading into the July 30 restart at Walt Disney World. The Kings, at 28-36, are hoping to make the playoffs for the first time since 2006.
The Athletic first reported that the Kings were closing their practice facility.
