BOSTON — The NFL remains aware of the investigation into Raiders head coach Tom Cable allegedly assaulting assistant coach Randy Hanson, and Cable would be subject to league discipline if it determines he violated the personal conduct code.

The Napa, Calif. Police Department has handed over its portion of the investigation to the district attorney, and NFL commissioner Roger Goodell said Tuesday he expects to receive what the findings were in the next few weeks.

"At that stage, we'll make a determination what our next step is," Goodell said.

Goodell added that one facet of the personal conduct policy is that the league gets involved more thoroughly in ongoing criminal investiagtions when there has been a pattern of early behavior, but with Cable there has not. This is the first incident that he is believed to have been involved in.

If Cable is found guilty of any crimes in the case, he would be subject to fines or suspensions from the NFL. However, criminal charges do not have to be brought against Cable for the league to take action against the coach.

Hanson told Yahoo! Sports recently that Cable threw him from his chair on Aug. 5 and threatened to kill him.

Raiders owner Al Davis is in Boston for the owners' meetings, but he made his way through the lobby of the Renaissance Waterfront Hotel without making comment on the Cable investigation.
