"The injury story line this week will revolve largely around who will be available in the Chargers' offensive backfield for Sunday's game against the Green Bay Packers.

Mike Tolbert, who tested his hamstring extensively at Arrowhead Stadium before Monday night's game, is expected to return.

The status of Ryan Mathews, who injured his groin and left Monday's game in the fourth quarter, and Curtis Brinkley, who suffered a concussion near the end of the game, won't be known until later in the week. It is feared that Mathews will miss his first game of the season."
