Seahawks, Chargers learning on job in exhibition

Seattle coach Pete Carroll realizes Tarvaris Jackson can't possibly be ready to run the Seahawks offense after just a handful of practices.

At least Carroll's quarterback won't be the only player learning on the job when the NFL finally returns Thursday for its first preseason games. Seattle visits the San Diego Chargers for the first nationally televised game of the year.

After the league's lockout wiped out most offseason activity and led to short training camps for all 32 teams, the NFL's exhibitions could be even more ramshackle than normal. With so little time to learn, rookies and newcomers will need every available snap in their four exhibition games to get ready for the season.

Jackson will start for the Seahawks, who jettisoned Matt Hasselbeck after a decade in Seattle.
