The NBA released the following statement on tonight's scheduled game between the Detroit Pistons and Denver Nuggets:
"The National Basketball Association game scheduled for tonight between the Detroit Pistons and Denver nuggets at Ball Arena has been postponed in accordance with the league’s Health and Safety Protocols.
Because of ongoing contact tracing within the Pistons, the team does not have the league-required eight available players to proceed with tonight’s game against the Nuggets."
Adrian Wojnarowski of ESPN added that Detroit returned a positive/inconclusive coronavirus test on a player. The Pistons were apparently watching pregame film, preparing for the game against Denver when they learned of the postponement. The league has recently made the decision to park teams in this situation over a single positive test.
