Kansas City came out in the third quarter with Succop's 38-yard field goal, yet the Cowboys began to take control as running back Tashard Choice got a 36-yard touchdown run.  In the fourth quarter, Dallas took the lead as Folk nailed a 28-yard field goal, followed by quarterback Tony Romo completing a 59-yard touchdown pass to wide receiver Miles Austin.  However, the Chiefs would tie the game with Cassel's 16-yard touchdown pass to wide receiver Dwayne Bowe.  In overtime, the 'Boys came out on top as Romo hooked up with Austin again on a game-winning 60-yard touchdown pass. Austin finished the game with 250 yards on 10 catches along with the two touchdowns, a Cowboy receiving record. With the win, the Cowboys went into their bye week at 3-2
