QB Philip Rivers gives RB Ryan Mathews the football.

Mathews, two days away from his first game in a Chargers uniform, got plenty of reps Thursday.

The backs as a whole, including RB Marcus Mason, carried the ball a good deal Thursday.

FB Mike Tolbert has completed a line of scrimmage hurdle and a sideline spin move at practice this week and also has been getting carries.

RB Shawnbrey McNeal tries to fend off coverage from LB Stephen Cooper, left, and LB Kevin Burnett.

Cooper eventually makes an interception.

WR Jeremy Williams, making a catch downfield Thursday, says he will ramp his intensity and that Saturday is more than just a preseason game to him.
