The Hornets announced the discipline on Sunday, saying that Posey would miss an important Southwest Division game against the San Antonio Spurs that night.
Posey was ejected during a Hornets' loss Friday night in New York against the Knicks after he threw the ball at feet of referee Gary Zielinski. Posey was reacting to a loose ball foul called against him as he was competing for a defensive rebound.
Posey is averaging 8.9 points and 4.9 rebounds. He is the Hornets' primary reserve, and New Orleans routinely relies on his defensive ability late in close games.
