Jan. 21 (UPI) -- The NBA has postponed the Memphis Grizzlies' next three games because the team doesn't have enough players to compete as a result of contact tracing for COVID-19, the league said Thursday.
Memphis also had a game postponed Wednesday because the team did not have the league-required eight players available to play the Portland Trail Blazers.
On Thursday, the league also postponed Friday's planned game between the Grizzlies and Blazers, as well as the Grizzlies' games Sunday and Monday against the Sacramento Kings.
The Grizzlies haven't played since Monday. Their next scheduled game is against the Chicago Bulls at 8 p.m. EST Wednesday in Memphis.
The postponed games are expected to be played in the second half of the NBA season.
The NBA has now had 20 games postponed due to positive COVID-19 tests and contact tracing since the season started Dec. 22. The second half of the 72-game season starts March 11.
The league said Wednesday that 11 of 502 players have tested positive for COVID-19 since Jan. 13.
