Coming off their thrilling overtime road win over the Redskins, the Cowboys went home, donned their throwback uniforms, and played a Week 12 interconference duel with the Miami Dolphins in the annual Thanksgiving game.  Dallas trailed early in the first quarter with Dolphins kicker Shayne Graham getting a 26-yard field goal, yet the Cowboys would answer in the second quarter with a 26-yard field goal from kicker Dan Bailey, followed by quarterback Tony Romo finding wide receiver Laurent Robinson on a 5-yard touchdown pass.  Miami would close out the half with Graham making a 28-yard field goal. The Dolphins retook the lead in the third quarter with Graham booting a 27-yard field goal, followed by quarterback Matt Moore completing a 35-yard touchdown pass to wide receiver Brandon Marshall.  Afterwards, Dallas regained the lead in the fourth quarter with Romo connecting with Robinson again on an 18-yard touchdown pass.  Miami struck back with Graham making a 23-yard field goal, but Bailey rescued the Cowboys by nailing the winning 28-yard field goal. Bailey (2/2 on field goal, including game-winning 28-yarder) and linebacker DeMarcus Ware (1 assist & a fumble recovery) were named NFL on CBS' All-Iron Award winners.
