The Giants would get on the board as quarterback Eli Manning found tight end Kevin Boss on an 18-yard touchdown pass, but the Eagles continued their scoring as McNabb completed a 54-yard touchdown pass to wide receiver DeSean Jackson and a 23-yard touchdown pass to wide receiver Jeremy Maclin. Philadelphia would begin the third quarter with an increase to their lead as Akers nailed a 35-yard field goal.
