Haywood v. National Basketball Association, 401 U.S. 1204 (1971), was a U.S. Supreme Court decision that ruled against the NBA's requirement that a player could not be drafted by an NBA team until four years after graduating from high school. Justice Douglas, in an in-chambers opinion, allowed Spencer Haywood to play in the NBA temporarily until the litigation could proceed further. The case was settled out of court, Haywood continued playing, and the NBA modified its four-year rule to allow players to enter the league early in cases of "hardship".
