FILE - In this Aug. 29, 2009, file photo, San Francisco 49ers quarterback Nate Davis (7) looks to pass during a preseason NFL football game against the Dallas Cowboys in Arlington, Texas. Davis is unfazed by a learning disability that makes it difficult for him to grasp the playbook and transfer that information onto the field. He carries himself with a confidence and poise in the huddle that has earned the former Ball State standout a job as the San Francisco 49ers' No. 3 quarterback. (AP Photo/Donna McWilliam, File)
