Practices are allowed to begin Sunday, but the Warriors are delaying their start until next Monday because of the positive tests.
The players in question could be eligible to return by the time the regular season tips off Dec. 22.
Under the NBA's COVID-19 health and safety protocols, a player who tests positive has to wait at least 12 days from the positive test or the onset of symptoms before he can return, per The Athletic's Sam Amick and Shams Charania. The player also requires clearance from his team physician and a physician representing the NBA.
The Warriors players in question will be unavailable for Golden State's first preseason game Dec. 12 against the Denver Nuggets.
When Utah Jazz stars Donovan Mitchell and Rudy Gobert tested positive in March, it was effectively enough to shut the league down indefinitely. The NBA then set up a tightly controlled environment at Walt Disney World Resort to limit any exposure to players, staffers and members of the media.
The health and safety protocols alluded to how the league isn't adopting as stringent an approach for the 2020-21 season:
"It is likely that some staff, players, and other participants in the 2020-21 season nonetheless will test positive or contract COVID-19, particularly as the virus remains prevalent in particular team markets and surrounding communities. The occurrence of independent cases (i.e., cases not spread among players or team staff) or a small or otherwise expected number of COVID-19 cases will not require a decision to suspend or cancel the 2020-21 season."
The NFL and MLB have staged their seasons at home markets rather than creating a bubble at one or more locations. Multiple teams from both leagues have experienced outbreaks, forcing the postponement and rescheduling of games. The same thing is unfolding in college football as well.
Tuesday's news serves as a reminder of what could be in store for the NBA until a COVID-19 vaccine is distributed on a mass scale.
