Ja Morant will miss at least the next two Memphis Grizzlies games, the team announced.
The point guard is under investigation by the NBA after he appeared to show a gun during an Instagram Live video at a nightclub on Saturday.
Morant's social media activity came a few hours after the 113-97 defeat to the Denver Nuggets, and he will now miss Sunday's meeting with the Los Angeles Clippers and Tuesday's face-off against the Los Angeles Lakers.
A statement from the Grizzlies read: "The Memphis Grizzlies announced today that Ja Morant will be away from the team for at least the next two games."
Earlier on Saturday, NBA spokesman Mike Bass confirmed the league was looking into the incident.
Last month, the NBA launched an investigation into a separate situation involving associates of Morant and members of the Indiana Pacers' travelling party in January.
It was alleged a red laser was pointed at the Pacers' team bus from a car Morant was a passenger in, with the Indiana group concerned the light may have come from a gun.
The NBA could "not corroborate that any individual threatened others with a weapon", the league finding "no evidence".
