AT&T stadium fell silent about halfway through the opening quarter, when Cowboys wide-receiver Allen Hurns completed a pass from quarterback Dak Prescott as he initiated contact with the Seahawks' defence. He also had a 44-yard run on their second quarter touchdown drive.
But Seattle's offense picked up some steam in the 2nd quarter with a pair of field goals by Sebastian Janikowski.
Still, the Seahawks took their first lead basically because the 40-year-old's injury forced them to try. A 34-yard completion from Prescott to Cooper gained much of the yardage in a nine-play, 67-yard drive that ended with a 1-yard TD run by Elliott that gave the Cowboys a 17-14 lead. Janikowski did not return and rookie punter Michael Dickson took over.
With Janikowski out, Seattle opted to attempt a 2-point conversion.
First, Elliott stiff-armed Shaquill Griffin on a 17-yard run to get inside the 20, then Prescott scrambled up the middle before a head-over-heels hit from Tedric Thompson at the Seattle 1. Seattle went up 14-10.
K.J. Wright intercepted Dak Prescott's pass in the end zone stopping a Dallas drive that was gaining momentum. Russell Wilson was playing his 13th playoff game and showed his experience by trying to rally the Seahawks. On the very next play, Wilson targeted Tyler Lockett, and the pair's flawless chemistry produced again for a 40-yard connection that put the Seahawks in the red zone. Seattle wasn't able to get the ball on an onside kick attempt.
Seattle made a last gasp run, though, thanks to a 53-yard pass from Wilson to Lockett, setting up an eventual J.D. McKissic 7-yard touchdown catch and Chris Carson two-point conversion run that made it a two-point game.
Dallas got into victory formation and ran out the clock to win 24 -22.
