Pre-game notes from Oakland

Posted by ESPN.com’s Bill Williamson

OAKLAND -- New Oakland defensive end Richard Seymour is warming up and looking very active. He is expected to play extensively.

It will be interesting to see Seymour go against San Diego center Nick Hardwick. Hardwick criticized Seymour for being a dirty player after the AFC championship game in Jan. 2008.

Both teams are wearing their throwback AFL uniforms. All of the Chargers are wearing black shoes.

It is about 70 degrees and clear skies in Oakland.

Rapper and actor Ice Cube was meeting and greeting players from both teams and fans prior to the game. He is doing an ESPN documentary on the Raiders during their days in Los Angeles.

Oakland running back Louis Rankin is expected to be Oakland’s kick returner.
