The Cowboys forced two turnovers during Sunday's 51-48 loss to the Broncos, but they failed to get the key third-down stop to allow the offense back on the field in the fourth quarter.
Facing third-and-1 from the Cowboys 2, Broncos running back Knowshon Moreno rushed for 1 yard to get the first down and cause Dallas to use its final timeout with 1:35 remaining. Quarterback Peyton Manning then ran the clock out by kneeling to set up the game-winning field goal by Matt Prater.
"It's disappointing because the offense, all the great plays they made throughout the day," Dallas linebacker Sean Lee said. "They continually brought us back in the game and when it mattered most, we couldn't get a stop. We couldn't stop them and that's the story of the game."
The Cowboys allowed the Broncos to score on 9 of 11 drives and pile up 517 total yards.
Manning fooled nearly everyone when he easily scored on a 1-yard run, a naked bootleg late in the second quarter.
It was his first rushing touchdown in five years, and to him it seemed like the yard was an eternity.
"It seemed like I had to run an awful long ways for 1 yard," Manning said.
Manning's teammates even had fun with the play.
"I saw his little Manning show," wide receiver Demaryius Thomas said referring to "The Book of Manning."
"I saw he had it in high school, and I've seen it a couple of times in practice. That's something he came up with himself. He did it this past week. It worked. Whatever works."
