An attorney representing injured Oakland Raiders assistant coach Randy Hanson will turn over medical records at the request of the Napa, Calif., police on Friday that show Hanson?s jaw is broken, multiple sources told the National Football Post. San Francisco attorney John McGuinn has been hired to represent Hanson, and police have been attempting to gain information from Hanson in recent days. Lt. Brian McGovern said earlier this week that if Hanson?s jaw is broken, it could lead to felony charges in the alleged assault that took place at the Raiders? training camp facility. The source said Hanson suffered a fracture in his upper jaw and that he had to seek additional emergency room treatment Wednesday night near his home in Livermore, Calif., for lower jaw pain two weeks after the incident. Cable has declined to comment on the matter, telling reporters it was an internal issue. However, NFL Security is investigating, and now law enforcement is expected to receive cooperation from Hanson and McGuinn, which will likely lead to an investigation three weeks before the beginning of the regular season. Police took a report about the incident on Aug. 6 at a hospital in Napa when Hanson was receiving X-rays. Any violation of the NFL?s personal conduct policy could lead to punishment from Commissioner Roger Goodell. The alleged assault took place Aug. 5 after Cable informed Hanson he would no longer be involved with coaching defensive backs on the field and would be relegated to film work, the source said.
