The NBA has announced the Memphis Grizzlies' next three games have been postponed in accordance with COVID-19 protocols.

Memphis had already seen Wednesday's scheduled meeting with the Portland Trail Blazers called off, the Grizzlies not having the league-required minimum of eight players available for action.

The same teams had been due to meet on Friday, however that clash will no longer be going ahead as planned.

Back-to-back games with the Sacramento Kings, set to take place on Sunday and Monday, are also postponed due to the combination of unavailable Grizzlies players and contact tracing for others on the roster. 

"The Memphis Grizzlies' next three games - Friday, January 22 at Portland and Sunday, January 24 and Monday, January 25 vs Sacramento - have been postponed in accordance with the NBA's health and safety protocols," the NBA said in a statement.

"The games are being postponed due to unavailable players for the Grizzlies and contact tracing for other players on their roster, and in order to ensure the health and safety of players on both teams."

In total, 20 games have been postponed during the NBA regular season as the competition deals with the ongoing impact of the coronavirus pandemic.

The Grizzlies are 7-6 on the season and on a five-game winning streak. Following the postponements, they are next due to be in action on January 27, when they host the Chicago Bulls.
