The NBA clash between the San Antonio Spurs and the Detroit Pistons has been postponed because of a positive coronavirus case.
A positive coronavirus test within the Spurs team will prevent them from having the league-required eight players available for Tuesday's game, the NBA says.
The postponement is the second this season for San Antonio (16-11) and third for Detroit (8-19).
Meanwhile, the NBA advised teams that players taking part in All-Star weekend in Atlanta will largely have to remain in their hotels when not at the arena.
Also, all players and coaches - whether part of All-Star events or not - will have to continue getting tested daily for COVID-19.
The NBA and the National Basketball Players Association agreed on those rules, the league said in a memo laying out the health and safety protocols that will apply during the break.
The first half of the season ends on March 4, and All-Star event participants arrive in Atlanta on March 6.
The game and skills contests are March 7.
For some teams NBA games will resume March 10 while for others they will recommence their campaigns on March 11 and March 12.
Players not participating in All-Star events may travel in the US, including Hawaii, Puerto Rico, and the US Virgin Islands, during the break.
However, they must obtain private accommodations for those trips, not hotels or resorts, and are "strongly recommended" to travel private as well.
