(TSX / STATS) -- DALLAS -- The Dallas Cowboys expected to rely on the run against a struggling Kansas City defense, but the trio of quarterback Dak Prescott and wide receivers Terrance Williams and Cole Beasley proved the unstoppable force in a 28-17 win over the Chiefs on Sunday.
Prescott completed 21 of 33 passes for 249 yards and two touchdowns, with Williams collecting nine catches for 141 yards and Beasley making two touchdown catches.
Prescott put the Cowboys on the board first, hooking up with Beasley on a 6-yard touchdown pass late in the first quarter.
A 38-yard field goal from Harrison Butker cut the lead to 7-3.
The Cowboys reclaimed the lead after a 61-yard drive capped by Prescott scrambling for a 6-yard touchdown run.
Dallas appeared poised to take a 14-3 lead into halftime with 21 seconds remaining in the first half. Prescott ended a seven-play, 82-yard drive inside the two-minute warning with a 10-yard scramble for a touchdown.
But Chiefs wide receiver Tyreek Hill kept the Chiefs in the game with a Hail Mary of sorts that left the 93,273 fans at AT&T Stadium speechless.
The Chiefs lined up at their own 44-yard line with two seconds remaining in the half. Dallas prepared for a heave downfield into the end zone with seven defensive backs lined up along the goal line.
Hill caught the pass from Alex Smith inside the Dallas 45-yard line and ran 20 yards before slowing down, allowing a team of blockers to line up in front of him. Hill followed the convoy, then used his speed and agility to burst through the Cowboys' secondary and into the end zone.
Kansas City received the second-half kickoff and took their first lead of the game. Smith found tight end Travis Kelce for a 2-yard touchdown pass that put the Chiefs ahead 17-14.
Dallas responded, however, marching 75 yards in 12 plays spanning nearly six minutes. Ezekiel Elliott finished the drive with a 2-yard run that put the Cowboys on top 21-17.
The Cowboys extended their lead thanks to a 7-yard touchdown pass from Prescott to Beasley, making it 28-17.
Elliott led the Cowboys in rushing with 93 yards on 27 carries with a touchdown.
Any chance for a Chiefs comeback ended on the team's next drive. Dallas safety Jeff Heath intercepted Smith to snuff out Kansas City's final scoring opportunity.
Smith finished 25-of-34 passing for 263 yards and two touchdowns.
