San Diego would deliver the opening strike in the first quarter as quarterback Philip Rivers completed an 81-yard touchdown pass to running back Darren Sproles.  The Ravens would respond with running back Willis McGahee getting a 5-yard touchdown run, yet the Chargers would regain the lead as kicker Nate Kaeding got a 29-yard field goal.  Baltimore would take the lead in the second quarter as McGahee got a 3-yard touchdown run.
