CHICAGO » The Bears and Raiders might both be using quarterbacks they didn’t plan to in their preseason game today.

Injuries to two Oakland quarterbacks could result in playing time for the recently acquired Colt Brennan. Chicago backup Caleb Hanie’s shoulder sprain might force the Bears into using Matt Gutierrez after only three days of practice with the team.

"We have a couple guys down, but we’re in decent shape," Bears coach Lovie Smith said. "We plan on playing our starters a little bit longer this week, getting into our normal routine of the second game of the preseason."

The Raiders’ offense suffered more setbacks this week when Charlie Frye underwent season-ending right wrist surgery and Bruce Gradkowski missed more time with a groin strain. Neither will play today, and Brennan, a Hawaii alumnus signed Aug. 7, will be the third QB.

Seahawks looking at WR Jackson

The Seahawks have been talking with the Chargers about acquiring unsigned wide receiver Vincent Jackson. So far it’s just talk.

A Seahawks spokesman said yesterday that Seattle was granted permission by the Chargers to talk to the representatives for the Pro Bowl wide receiver and restricted free agent a couple of weeks ago.

But nothing has changed. There is apparently no deal imminent, Jackson’s price tag remains high and he still has not reported to training camp because he is unhappy with being a restricted free agent in San Diego.
