NORMAN - Prosecutors weeks ago declined to file sexual assault charges against Oklahoma starting linebacker Frank Shannon, Cleveland County District Attorney Greg Mashburn said Thursday.

The district attorney said Shannon was not charged based on the woman's wishes at the time and based on the facts that were presented.

He explained the woman said she did not want Shannon prosecuted. He also said it was unclear from the accounts of both the woman and the player "what had actually taken place."

Shannon's future at the University of Oklahoma will be determined through an appeals process there over the allegation that he sexually assaulted a female student at his off-campus apartment early on the morning of Jan. 20.
