Raiders news and notes

Posted by ESPN.com's Bill Williamson

While covering the Chiefs' camp, I have kept up to date to what has been happening in Oakland.

According to an NFL source, Oakland receiver Chaz Schilens was set to have surgery on his broken foot Wednesday. He broke the foot in practice Tuesday. Schilens, the Raiders' No. 1 receiver, is expected to be out 6-8 weeks.

However, these types of injuries can often linger. The Raiders will miss Schilens no matter how long he will be out. He was having an excellent training camp.

Meanwhile, top pick Darius Heyward-Bey will be asked to step it up with Schilens out. Heyward-Bey's hands have become an issue again. He dropped at least five passes in the two practice days against San Francisco.

The Oakland Tribune reports that the Raiders' offense struggled mightily against the 49ers' defense on Wednesday. Oakland quarterback JaMarcus Russell was intercepted three times. San Francisco cornerback Dre' Bly said it was "total domination."

What does this mean? Not much. The Raiders' offense and Russell had a bad day. No big deal if improvements are made. But this did make Saturday's preseason game between the two teams more interesting.

Rookie safety Mike Mitchell's hamstring injury could potentially endanger his chances of playing in the regular season opener.
