The Suns are now the latest NBA team to deal with contact tracing issues related to the coronavirus pandemic, and their game Wednesday against the Hawks was called off by the league after it was learned they wouldn’t have enough players cleared to participate.

The NBA also revealed Wednesday that 16 players — by far the most in a one-week period since training camps started — returned positive COVID-19 tests between Jan. 6 and Tuesday. With 497 players tested, that reflects a positivity rate of 3.2%.

In the previous five weeks combined, only 15 players were positive.

That Suns-Hawks game was the third on Wednesday’s schedule to be called, joining the Jazz-Wizards and Magic-Celtics. It also marks the second consecutive time that a team ran into issues after playing in Washington; the Heat lost eight players to COVID-related issues following their road game against the Wizards on Saturday.

Also not playing Wednesday: Zion Williamson, ruled out by the Pelicans for their road game against the Clippers because of the league’s protocols. Pelicans coach Stan Van Gundy said, the issue was an inconclusive test.

Friday’s Wizards-Pistons and Warriors Suns matchups also were called off.
