Ja Morant says he made a "bad mistake" but now realises what he has to lose following a series of poor off-court decisions leading to his eight-game NBA suspension.

The NBA announced the suspension without pay for Morant on Wednesday for carrying a gun in a Denver nightclub in an incident that the Memphis Grizzlies guard posted in an Instagram Live video earlier this month.

Morant, who has been away from the Grizzlies since the March 4 incident and underwent counselling during his absence, will receive credit for the five games he has already missed and will be eligible to return for Memphis' March 20 home game against the Dallas Mavericks.

The latest incident is the latest in a pattern of behaviour from Morant, who met with NBA commissioner Adam Silver on Wednesday after the league's damning condemnation of his "irresponsible, reckless and potentially very dangerous" conduct.

"I realise what I have to lose, and for us as a group, what we have to lose," Morant during an interview with ESPN's Jalen Rose. "It's pretty much just that being more responsible, more smarter and staying away from all the bad decisions.

"I feel like in the past we didn't know what was at stake. And now finally me having that time to realise everything, have that time alone, I realise that now."

Morant showed remorse for his actions at the nightclub, clarifying that he did not own the gun in the video, while adding that the behaviour did not represent him truly.

"It's not who I am," Morant said." I don't condone it or any type of violence, but I take full responsibility for my actions. I made a bad mistake.

"I can see the image that I painted over myself with my recent mistakes. But in the future, I'm going to show everybody who Ja really is, what I'm about and change this narrative that everybody got."

Morant has spent time away from the Grizzlies since the incident reflecting on his behaviour, including undertaking a counselling program in Florida.

"I feel mentally good that I haven't been in many years," Morant said. "I'm in a space where I'm very comfortable.

"I was constantly talking to therapists. I've been doing Reiki treatment. I've been doing anxiety breathing, different stuff to help me manage that and release all that stuff from my body.

"I made a terrible mistake being inside a club and went Live. I put myself in a bad position."

The Grizzlies have gone 3-3 in Morant's absence, sitting third in the Western Conference with a 41-27 record.
