Ja Morant went to his weapon wheel for his latest celebration ... electing for a "grenade" instead of his go-to "gun" gesture in Tuesday night's game.
The Memphis Grizzlies star debuted the move against the Charlotte Hornets at the Spectrum Center ... days after he was handed a $75,000 fine for pretending to unload a firearm on multiple occasions in competition, which the NBA publicly warned him to stop doing.
Morant apparently can't help but channel his inner "Call of Duty" as he goes to war on the court .
