Contact tracing issues for the Memphis Grizzlies meant they would not have enough players eligible to play in Portland on Wednesday night, leading to the 16th game postponement for coronavirus-related reasons by the NBA this season.

Also Wednesday: The NBA said 11 new players in the past week have tested positive for COVID-19, down from 16 the previous week but still higher than what the norm has been since training camps opened in early December.

Of the 16 postponements, 15 have come since Jan. 10 and the number could rise again soon — since Memphis is also scheduled to play in Portland on Friday. The league has not made any announcement about that game.
