From RealGM:
David West of the New Orleans Hornets has been suspended one game without pay for striking Mike Miller of the Minnesota Timberwolves in the head, it was announced today by Stu Jackson, NBA Executive Vice President, Basketball Operations.
West was ejected from Sunday’s game against Minnesota after clubbing Miller from behind late in the second quarter. Miller was knocked hard to the court by the foul, but didn’t appear to be injured on the play.

West did not receive an additional fine with the suspension.
