Brooklyn Nets star Kyrie Irving will remain absent and there is no timeline for a return as the team and NBA review videos circulating on social media.
Irving will sit out his fourth consecutive game on Tuesday due to personal reasons amid the emergence of videos that appeared to show the six-time All-Star without a mask at a family birthday party.
The NBA's coronavirus protocols ban players from entering clubs, bars and lounges, while they are also forbidden from attending social gatherings of more than 15 people.
Nets general manager Sean Marks addressed the situation in a statement on Tuesday, prior to Brooklyn's matchup against the Denver Nuggets.
"We are aware of a video on social media featuring Kyrie Irving at a family gathering," Marks said.
"We are reviewing the circumstances with both Kyrie and the NBA in order to determine compliance with health and safety protocols.
"Kyrie remains away from the team due to personal reasons. A date of his return has yet to be finalised. In the meantime, we will continue to stay focused on our organisational goals.
"Kyrie will have the opportunity to address his absence when he is ready to do so."
Irving is averaging 27.1 points, 6.1 assists and 5.3 rebounds per game for the Nets (5-6) this season.
