The Memphis Grizzlies suspended Ja Morant from all team activities after a video of the star guard brandishing a gun surfaced on social media Saturday night.
The Grizzlies announced the suspension, which is subject to a league review, in a statement issued Sunday, two months after the NBA penalized Morant for a similar incident.
"We are aware of Ja Morant's social media post and are gathering additional information," NBA spokesperson Mike Bass said in a statement Sunday.
On Saturday, during an Instagram Live session on Morant's friend Davonte Pack's account, the All-Star displayed a handgun while driving and sang along to a rap song.
Morant departed the Grizzlies and joined a treatment program in March after a video surfaced of him carrying a gun while intoxicated at a Denver club while the team was in town to play the Nuggets.
He was later punished for eight games after meeting with NBA commissioner Adam Silver, who deemed Morant's actions "irresponsible, reckless, and potentially very dangerous."
At the time of the ban, Morant told ESPN in an interview that he understands "what I have to lose" and that he will strive to be "more responsible, smarter, and staying away from all the bad decisions."
Morant has been involved in multiple off-court confrontations in the last year. A high school prospect is suing him following a confrontation during a pickup game in Morant's backyard in which Morant and Pack are accused of punching the boy in the head.
