Ja Morant's been laying low, but the Grizzlies superstar just made a rare appearance, surprising a bunch of kids at a Memphis basketball court ... hooking everyone up with his signature Nike kicks during hoop sesh!
24-year-old Morant, who will serve a 25-game suspension to start the season, along with Nike held the "Only Basketball" event this week ... and as you'd expect, the kids were super hyped when the 2x All-Star pulled up to the gym.
