Joakim Noah of the New York Knicks was suspended 20 games without pay for violating the league's anti-drug policy.
He tested positive for a substance found in some over-the-counter supplements, the league said Saturday.
Noah has not played since Feb. 4 and likely was to miss the Knicks' final 10 games this season because of a left knee injury. The NBA said Noah's suspension "will begin with the first NBA regular season or playoff game for which he is eligible and physically able to play."
