Oakland news and notes

Posted by ESPN.com’s Bill Williamson

• Oakland defensive assistant Randy Hanson is getting aggressive while he waits to see whether the Napa, Calif., district attorney’s office will file assault charges against Oakland coach Tom Cable.

Hanson said he is willing to take a lie detector test to show he is telling the truth. Hanson maintains Cable assaulted him at the Raiders’ training camp Aug. 5 and that he suffered a broken jaw in the incident.

The Napa police handed the case over to the DA's office nearly two weeks ago. A filing decision could come as soon as Monday. In a taped message on a media information phone line, Napa DA Gary Lieberstein advised media earlier this week to check back Monday.

• Oakland receiver Javon Walker says he is not adverse to a trade if the Raiders want to deal him. That’s fine. But it’s doubtful any team would want to make a move for the oft-injured Walker, who has played four snaps this season.

• Chaz Schilens told reporters Thursday that he may not be ready to play Sunday against Philadelphia. He has been out eight weeks with a broken foot.
