Just after the two-minute warning in the first half of the Cowboys matchup with the Minnesota Vikings, they were facing third and seven on the 22-yard line. After falling behind by 14 points to start the game, a touchdown here would tie the game for the Cowboys.
They came out in an empty formation with two receivers spread out to the left, three receivers spread out to the right and no one but quarterback Dak Prescott in the backfield.
The Vikings walked two players up into the A gaps - showing a double A-Gap blitz.
