Brett Maher kicked a 39-yard field goal for Dallas and Sebastian Janikowski answered for Seattle from 27 and 42 yards, but hurt his left leg on a 57-yard miss to end the first half, forcing the Seahawks to chase touchdowns and two-point conversions in the second half.
Dallas' defense came through again, though, forcing a punt and giving Elliott and Prescott a highlight play apiece on a drive to Prescott's 1-yard sneak for a 24-14 lead with 2:08 remaining. The Texans condensed only in the fourth quarter on a 21:7, but had no Chance on the quarter-finals.
Dallas' defense, ranked in the top 10 most of the season, mostly kept quarterback Russell Wilson under control and handed him his first loss in four wild-card games. Each had a sack in Philadelphia's 16-15 victory at Chicago.
The NFL's Wild Card weekend kicks off today with a pair of intriguing Saturday matchups. Seattle's 24-22 loss at Dallas ended a run of nine straight victories in playoff openers. Dak Prescott ran off himself with the Ball and jumped in the direction of the end zone, but Seattle's Tedric Thomson threw itself onto the legs of the Dallas Quarterbacks.
The Chargers have 38 sacks on the season, as their defensive front is led by Melvin Ingram and Joey Bosa. The victor of that game will then take on the victor of the Chiefs vs. Colts divisional game to determine the AFC championship game.
The Patriots have proven themselves formidable at home, averaging 32.9 points and winning all but two of their eight games by double figures. Only Hall of Famer Terrell Davis (142.5) has averaged more in the playoffs since 1970.
In the AFC, the Andrew Luck-led Indianapolis Colts travel to Houston where they will take on a Texans team that has been red-hot after a 0-3 start to the season.
Meanwhile, Terri Valentini, the league's first female instant replay official, will also achieve an NFL first when she works the playoff game between the Indianapolis Colts and the Kansas City Chiefs on Saturday, according to Yahoo Sports.
