New York, NY (Best E Casino) - Boston Celtics forward Kevin Garnett has been suspended for one game without pay for throwing a punch at Milwaukee Bucks center Andrew Bogut.

In the Celtics' 102-97 overtime victory over Milwaukee on Saturday, Garnett reached out with his left arm and smacked Bogut in the forehead with 3:58 left in the fourth. Bogut had elbowed Garnett during a play under the basket, and both players received technical fouls in the altercation.

Bogut had already received one technical foul at that point and was ejected. His foul on Garnett was upgraded to a flagrant foul penalty one, which is assessed whenever a player makes unnecessary contact with another player.

Garnett will serve his suspension on Tuesday, when the Celtics take on the Knicks at TD Banknorth Garden.

In a season after winning his first championship, Garnett has averaged 16.3 points and 9.8 rebounds in 11 games this year. Bogut has averaged a double- double in 11 games with 11.2 points and 10.4 rebounds.
