Knicks star Carmelo Anthony has just been suspended for one game -- WITHOUT PAY -- for confronting Celtics player Kevin Garnett Monday night ... in an epic expletive-filled standoff.
TMZ posted the video ... showing 'Melo waiting for KG in the arena tunnel at Madison Square Garden ... after the two had been going at each other during the game.
'Melo had said KG insulted him on the court and said things that "crossed the line." There are reports that KG said Anthony's wife "tastes like Honey Nut Cheerios" ... but neither player has confirmed exactly what words were exchanged.
According to the NBA, Carmelo will serve his suspension on January 10th when the Knicks face the Pacers.
A rep for the league released a statement, saying, "There are no circumstances in which it is acceptable to confront an opponent after a game."
