Knicks forward Carmelo Anthony has been suspended one game by the NBA for confronting Kevin Garnett after New York’s loss to Boston on Monday.

Anthony, who was angry about Garnett’s choice of words during a fourth-quarter altercation, went toward the Celtics’ locker room after the game and later waited for Garnett outside Boston’s team bus.

Anthony didn’t believe he would be suspended because he was just looking to talk to Garnett, not have an altercation. But NBA executive vice-president of operations Stu Jackson said on Wednesday there were “no circumstances in which it is acceptable for a player to confront an opponent after a game.”
