A spokesman for the Rockets says White, whose acknowledged anxiety disorder has kept him from playing for Houston this season, is still on the Rio Grande Valley Vipers roster. The spokesman said the Rockets would have no further comment.

White played high school basketball at DeLaSalle in minneapolis until he was asked to leave the school and then played for Hopkins. He left the University of Minnesota after one season, during which he was not allowed to play because of off-the-court issues, and then played for one season at Iowa State.

He was drafted by Houston last June.
