Trial of Oklahoma State's Williams postponed

A judge has delayed the trial of a suspended Oklahoma State basketball player accused of sexually assaulting two women.

STILLWATER, Okla. -- A judge has delayed the trial of a suspended Oklahoma State basketball player accused of sexually assaulting two women.

Darrell Williams' trial was postponed by a week until July 9, the Stillwater NewsPress reported.

Payne County District Judge Phillip Corley says the delay is necessary because a prosecution witness will be out of the country.

Two women allege that Williams assaulted them at an off-campus party in 2010. He's charged with four counts of rape by instrumentation and one count of sexual battery.

Prior to his suspension, Williams averaged 7.1 points and 7.3 rebounds per game.
