The Dallas Cowboys are desperate to get into the playoffs this season, and that need propelled head coach Jason Garrett to go for a first down on a fourth-down play late in the fourth quarter.
With inches to go, quarterback Dak Prescott attempted to sneak for the first down. He lunged forward, was stopped and lunged again.
The officials placed the ball right on the first-down line and called for the marker. When referee Gene Steratore finished his inquiry, he couldn't tell whether the Cowboys had gotten it.
So, he slid a piece of paper between the nose of the football and the last link. The paper test resulted in a first down, and that led to a go-ahead field goal.
