Former San Francisco 49er Dana Stubblefield was sentenced to 15 years to life in prison Thursday for raping a developmentally disabled woman who prosecutors said he lured to his home with the promise of a babysitting job. The sentence was issued by a judge in San Jose after denying a defense motion for a new trial, the Mercury News reported. Last week, the Sixth District Court of Appeal denied a related petition filed on behalf of Stubblefield by his attorneys.
