David Buehler connected on his second field goal of the day, a 46 yarder, to give the Cowboys a 20-14 lead in the third quarter.
The Cowboys nine play, 36 yard drive stalled after Jon Kitna threw a pair of incompletions to Austin Miles. Kitna narrowly missed hooking up with Miles on a touchdown pass but the ball was slightly overthrown and just out of the reach of Miles.
Dallas now leads Indianapolis 20-14.
