The National Football Post blog report names Raiders head coach Tom Cable as the attacker who broke Hanson's jaw during an altercation at the team's training camp facility Aug. 5 in Napa.

Cable said the matter remains an internal issue that he does not want to discuss. He previously said that "nothing happened" when pressed for details.

"The one thing I will tell you is, when all the facts come out, everything will be fine," Cable said in his daily news conference after practice Thursday.

Cable said he was unaware of any police or NFL investigations into the incident, which was first reported Monday. A league spokesman said Tuesday the league would look into the matter.

Hanson could not be reached for comment. A receptionist at the team facility in Alameda said he was unavailable for any phone calls.

The NFP story cited unidentified sources who gave a detailed account of what seemed to be Hanson's side of the story. The sources said Cable knocked Hanson out of his chair and into a cabinet, choked him on the ground and threatened twice to kill him before other coaches broke it up.

Hanson now wants to meet with police, according to the story, because Raiders owner Al Davis refused to let him remain on the coaching staff. The report said Cable recently demoted him to film work.

Police said the victim initially refused to cooperate with their investigation. They learned of the assault when he sought treatment at a Napa hospital and interviewed him there.

Napa Police Lt. Brian McGovern said he was aware of the media report but that the case remains closed until the victim pursues charges. The story said Hanson would release his medical records to police today.

If reports that Hanson has a fractured jaw are true, potential charges could elevate from a misdemeanor to a felony because it involves great bodily harm.

Police would then re-open the investigation as they conduct interviews and review evidence. They will then hand their findings over to the district attorney, who will determine if the case merits charges.

"At this point, there is nothing new on our end of it," McGovern said. "I don't have any different information."

Any crime committed by an NFL employee, including head coaches, would be considered a violation of the league's personal conduct policy.

With or without criminal charges, NFL Commissioner Roger Goodell has the authority to impose a fine and/or suspension on anyone he determines broke the rules.

Briefly: The Raiders had a light practice with 21 players sitting out to rest injuries, or just rest, after consecutive two-a-days with the 49ers. ... Rookie wide receivers Louis Murphy and Darrius Heyward-Bey will start Saturday's exhibition game against the 49ers. ... Darren McFadden or Michael Bush will get the next turn at starting running back ahead of Justin Fargas.
