Lakers guard Wayne Ellington just got slapped with a $20,000 fine by the NBA ... after he threatened to put his "hands on" Facundo Campazzo following an incident between the two during a game over the weekend.
NBA exec Byron Spruell announced the fine on Wednesday afternoon ... reprimanding Ellington for his threatening tweet.
If you missed it, during the Lakers vs. Nuggets game on Sunday, Campazzo intentionally shoved Ellington in the back -- sending him crashing to the floor.
