The Cowboys regained the lead as quarterback Tony Romo completed a 42-yard touchdown pass to wide receiver Miles Austin. Dallas increased their lead in the third quarter as Romo completed a 66-yard touchdown pass to wide receiver Roy Williams.  In the fourth quarter, Tampa Bay answered with running back Derrick Ward getting a 1-yard touchdown run, yet the Cowboys struck right back with Romo completing an 80-yard touchdown pass to wide receiver Patrick Crayton, along with running back Marion Barber getting a 6-yard touchdown run.
