The Chargers will be without inside linebacker Tim Dobbins for at least two weeks due to a knee injury.  He has played in 7 games (2 starts) for the Chargers this season and he has 33 tackles, 1 tackle for a loss, 1 pass defensed, 1 sack and 1 interception.  Brandon Siler will start if Kevin Burnett is not ready to return from injury.  Siler has played in 7 games (0 starts) this season for the Chargers and he has 22 tackles and 1 tackle for a loss.  Kevin Burnett has missed the last two games due to a ankle injury but he’s getting close to returning to action.  Burnett has played in 5 games (all starts) this season for the Chargers and he has 32 tackles, 1 tackle for a loss and 1 sack.  The Chargers really need Burnett ready to go as Siler would have a rough time dealing with Brandon Jacobs and Ahmad Bradshaw this week.
