BOSTON — Oakland Raiders coach Tom Cable will be subject to NFL discipline if he is implicated by police in their investigation of an alleged assault on an assistant coach.

Commissioner Roger Goodell said Tuesday that workplace violence is specifically identified in the league’s personal conduct policy, and if Cable is charged with any crimes, he could be punished by the NFL.

Goodell expects to receive a report ‘‘in the next couple weeks’’ on the Napa, Calif., police investigation, which is in the hands of the district attorney. He said the league is ‘‘allowing the criminal process to go forward for some period of time’’ before potentially getting involved.

‘‘What are the facts?’’ Goodell asked at the fall owners meetings. ‘‘There’s a legal and criminal process going on to determine what are the facts.’’

But criminal charges need not be brought against Cable for the NFL to discipline him if he broke the league’s conduct rules.

Defensive assistant Randy Hanson has alleged that he was punched by Cable during training camp and his jaw was broken. Hanson also has claimed Cable threatened to kill him during the August attack.

Cable has denied the allegations and has been advised to stay silent.
