Oakland added onto their lead in the second quarter with kicker Sebastian Janikowski getting a 23-yard field goal, followed by quarterback Carson Palmer completing a 33-yard touchdown pass to wide receiver Denarius Moore. The Chargers began the third quarter with quarterback Philip Rivers finding rookie wide receiver Vincent Brown on a 30-yard touchdown pass, but the Raiders struck back with Palmer completing a 26-yard touchdown pass to Moore.  Afterwards, San Diego closed out the quarter with Rivers hooking up with fullback Jacob Hester on a 7-yard touchdown pass.  The Chargers tried to rally in the fourth quarter, but Oakland's defense held on to preserve the win. Win the loss, not only did San Diego fall to 4-5, but it marked the first time since 2003 that the Chargers had lost four-straight.
