Ja Morant is countersuing the teenager who says he was assaulted by the NBA star ... claiming the guy is lying about their July 2022 pickup basketball altercation -- alleging he's the one who was actually threatened during the incident.
The Memphis Grizzlies point guard spelled out his claims in new court documents that were filed in Shelby County, Tenn. on Wednesday night.
In the docs, obtained by TMZ Sports, Morant acknowledged getting into a tiff with H.S. basketball star Joshua Holloway during the July 26 game at his home in Memphis, but says Holloway was the aggressor in the situation.
