The Cowboys went three-and-out on their first possession, with Dak Prescott overthrowing a wide-open Michael Gallup that might have gone for a touchdown on the first play. The Chiefs went 86 yards on nine plays for an opening touchdown.
The Chiefs then forced the Cowboys into a third-and-14 at the Kansas City 21. Frank Clark sacked Prescott, forcing a fumble. Chris Jones picked it up but went backward 2 yards with the recovery.
The Chiefs could not convert it into a touchdown, settling for a 37-yard field goal by Butker with 7:55 remaining in the first quarter.
The Cowboys have two possessions, six plays and 3 yards.
