What Raiders head coach Tom Cable referred to Monday as "an internal issue" may be about to go external. Or maybe infernal.

The NFL-themed Web site National Football Post, citing an unnamed source, reported Thursday that injured Raiders assistant coach Randy Hanson is prepared to turn over medical records to Napa police, initiating an investigation that could lead to Cable being charged with felony assault.

The Web site also said that Hanson has hired San Francisco-based attorney John McGuinn and that the medical records will show that the defensive assistant coach suffered a fracture in his upper jaw.

It also reported Hanson, suffering from lower-jaw pain, had to seek additional emergency room treatment Wednesday night near his home in Livermore.

The Web site also offered new details on the Cable-Hanson incident.

Citing its source, the National Football Post said Cable and Hanson met Aug. 5 with defensive coordinator John Marshall and defensive backs coaches Lionel Washington and Willie Brown in a room at the Napa Valley Marriott to discuss a plan to reduce Hanson's role with the team.

As Hanson heatedly addressed Marshall, Cable came up behind Hanson and knocked him out of his chair and into a cabinet, the Web site said.

Cable and Hanson fell to the floor, where Cable began to choke the smaller man, according to National Football Post.

"I am going to kill you, I am going to kill you," Cable said as he choked Hanson, the Web site said.

The other coaches pulled Cable off Hanson, but Cable went after Hanson again, according to the report.

The next day, Hanson was examined by doctors at Queen of the Valley Medical Center in Napa, which in turn notified police as dictated by hospital protocol.

Hanson declined to cooperate with police then but apparently has changed his mind.

Napa Police Lt. Brian McGovern told the Contra Costa Times on Thursday that police haven't heard from Hanson about turning over the medical records and filing a complaint.

"If the victim were to come forward and indicate he wanted to pursue the case criminally, we would conduct an investigation which would include any potential witnesses," McGovern said. "We'd gather that information, get it to the district attorney for review and determine if the case warranted the filing of charges."

Attempts to reach Hanson's lawyer, McGuinn, for comment were unsuccessful.

After practice Thursday afternoon, Cable was not as tight-lipped as he had been throughout the week. But he still refused to divulge any details of the fracas.

"Yeah, we're still going to take care of it internally," Cable said. "The one thing I will tell you is when all the facts come out, everything will be fine."

Asked whether the Raiders had been contacted by Hanson's lawyer or by police, Cable said: "I don't know any of that."

About an NFL investigation?

"I don't know that, either," Cable said.

A Raiders source told The Press Democrat that the team had not heard from Hanson's representatives. The source said word of an NFL investigation might be forthcoming within a few days.

On Tuesday, NFL spokesman Greg Aiello wrote in an e-mail that "we are looking into it so that we can understand the facts."

The NFL's personal conduct policy, which has become an area of emphasis under Commissioner Roger Goodell, could put Cable in hot water even if charges aren't filed. The list of circumstances that may incur discipline includes "violent or threatening behavior, whether in or outside the workplace."

The code also states "the league must be advised promptly of any incident that may be a violation of this policy." It is unclear whether the Raiders informed the NFL of the Hanson incident.

The National Football Post said Raiders owner Al Davis met Saturday with Hanson in Alameda and offered him the choice of joining the scouting department, breaking down film or doing nothing but still get paid.

Hanson, hired by Davis in 2007, reportedly balked at all three because none involved coaching. On Sunday, Davis called Hanson to talk to him again but Hanson hanged up, according to the Web site.

As the media circus has swirled around the Raiders, players have tried to focus on football. Most seem sincerely clueless about whatever happened between Cable and Hanson.

"It has never been a distraction," backup quarterback Jeff Garcia said Thursday. "It's been something that's been kept really low, that's why it hasn't been a distraction. It's unfortunate what happened."
