From NBA office: 

New York Knicks' forward Carmelo Anthony has been suspended for one game without pay for confronting Boston's Kevin Garnett in the arena tunnel, near the players' locker rooms, and in the parking garage following the Celtics at Knicks game on January 7, it was announced today by Stu Jackson, NBA Executive Vice President Basketball Operations.

"There are no circumstances in which it is acceptable for a player to confront an opponent after a game," Jackson said. "Carmelo Anthony attempted to engage with Kevin Garnett multiple times after Monday's game and therefore a suspension was warranted."

Anthony will serve his suspension on January 10 when the Knicks play the Indiana Pacers at Bankers Life Fieldhouse.

Anthony became irate during the game, after Garnett allegedly said something untoward about Anthony's wife LaLa. Anthony then confronted Garnett in the arena tunnel and waited for him near the Celtics departing team bus. The NBA has sent its message.
