Philadelphia took the lead in the second quarter as kicker David Akers made a 33-yard field goal, followed by running back LeSean McCoy's 29-yard touchdown run.  Afterwards, San Francisco closed out the half with kicker Joe Nedney booting a 50-yard field goal.  After a scoreless third quarter, the Eagles would add onto their lead in the fourth quarter as safety Quintin Mikell returned a fumble 52 yards for a touchdown.  The Niners began to rally as Smith found tight end Vernon Davis on a 7-yard touchdown pass, yet Philadelphia answered with a 45-yard field goal from Akers.
