Hoping to build on their home win over the Jets, the Browns flew to Qualcomm Stadium to take on the throwback-clad San Diego Chargers.  In the first quarter, things started off close with Chargers kicker Nate Kaeding getting a 29-yard field goal, while Browns kicker Phil Dawson nailed a 37-yarder.  In the second quarter, Dawson would get a 20-yard field goal for Cleveland.  However, San Diego got the first touchdown of the game, as LB Marques Harris recovered a fumble in the Browns endzone for a touchdown.  Dawson would supply the scoring for Cleveland for the rest of the half, as he nailed a 42-yarder and a 30-yarder.  In the third quarter, the Chargers gained some momentum, as RB LaDainian Tomlinson, after getting bottled up in the first half, broke out with a 41-yard TD run for the only score of the period.  In the fourth quarter, Dawson would get another field goal, which came from 36 yards out.  However, San Diego would respond with Tomlinson getting a 7-yard TD run.  Cleveland would have Dawson get a 35-yard field goal, yet Tomlinson would get an 8-yard TD run, which was followed by a successful two-point conversion from QB Philip Rivers to WR Vincent Jackson.  The Browns would finally get a touchdown, as QB Charlie Frye completed a 4-yard TD pass to WR Braylon Edwards.  Unfortunately, the damage was already done.  With the loss, Cleveland would fall to 2-6.
