Jason Avant's nine-yard touchdown reception from Donovan McNabb tied the game, and in the third quarter, David Akers made his second field goal from 47-yards out to make it 13-10 Philadelphia. Favre responded with a 13-play field goal drive to even the score. Later, J. R. Reed muffed a punt and the Packers recovered at the Eagles 31-yard line and Mason Crosby kicked a 42-yard game winner.
