SAN FRANCISCO (AP) — The National Football League on Thursday is expected to ask a federal judge to dismiss a lawsuit filed by former players who say team officials gave them powerful painkillers and other drugs to keep them on the field without regard for their long-term health. NFL lawyers in court papers deny the allegations and argue that the former players waited too long to file the lawsuit. In court papers, the NFL lawyers say the lawsuit doesn't specify what damage the former players have suffered and who exactly dispensed the painkillers at the heart of the complaint.
