Philadelphia's Carson Wentz threw for 319 yards and a touchdown Sunday as the Eagles won a gritty 17-9 home victory over Dallas, seizing command of their NFL playoff-berth battle.

"Resilient bunch. Man goes down. Next man up. Guys keep believing. We never look down. We just keep going."
Philadelphia seized the lead on Jake Elliott's 36-yard field goal, and Wentz later flipped a 6-yard touchdown pass to Dallas Goedert for a 10-0 lead.
Kai Forbath answered for Dallas with second-quarter field goals of 32 and 49 yards to lift the Cowboys within 10-6 at half-time.
Wentz drove the Eagles 80 yards in 10 plays late in the third quarter, and Miles Sanders capped the march with a 1-yard touchdown run as Philadelphia took a 17-6 edge.
Forbath kicked another 49-yard field goal, and Dallas drove 65 yards in 11 plays late only for Eagles cornerback Sidney Jones to break up Dak Prescott's fourth-down pass to Michael Gallup in the end zone to foil the final Dallas threat.
"The sky is the limit for this team," Eagles coach Doug Pederson said. "I'm so happy."
