In my wildest dreams, I never thought I'd have to set up a Twitter account to defend myself. In the most possible straightforward and honest manner, I did not do this.@espn — Rodney Anderson (@24RAnderson) December 5, 2017

NORMAN, Oklahoma -- The district attorney's office of Cleveland County, Oklahoma, determined that criminal charges were not warranted against University of Oklahoma running back Rodney Anderson after a police investigation into whether he sexually assaulted a woman who filed an emergency protective order against him.Assistant district attorney Greg Mashburn said during a news conference that the evidence, which included interviewing friends and surveying text messages exchanged between the two, suggested the sexual encounter was consensual."There are certainly cases where we just simply can't prove something and we will decline to pursue charges due to insufficient evidence," Mashburn said. "But I think in this case, it was important for us to tell the whole story so people understand the facts that were presented to us."The petition filed Monday says the 21-year-old Rodney Anderson walked the woman home after she had been drinking on Nov. 16. It says the woman remembers kissing Anderson and vomiting.The woman says she later recalled Anderson forcing himself on her and "feeling like I couldn't get away."In a statement, Anderson's attorney, Derek Chance, says the allegations are "patently false" and that Anderson is "shocked and disturbed" by the claims.Anderson leads the Sooners with 960 yards rushing and 11 touchdowns and has 283 yards and five touchdowns receiving.
