ARLINGTON, Texas — Dak Prescott led scoring drives on all four Dallas possessions in the first half before throwing his first career touchdown pass, and the Cowboys beat the Chicago Bears 31-17 on Sunday night to snap an eight-game home losing streak.

With his second straight win, Prescott doubled the number of victories the Cowboys (2-1) had in 14 games without injured quarterback Tony Romo over the previous three seasons.

Prescott’s first TD pass was a 17-yarder to Dez Bryant for a 31-10 lead in the fourth quarter, and he’s up to 99 throws without an interception to start his career.

Brian Hoyer had trouble moving the Chicago offense early with Jay Cutler sidelined because of a sprained right thumb, and the Bears fell behind 24-3 at halftime. They dropped to 0-3 for the second time in two seasons under Coach John Fox.

Hoyer was 30 of 49 for 317 yards and two touchdowns to Zach Miller. Most of his yardage came in the fourth quarter with the game out of reach.

Ezekiel Elliott, the fourth overall pick in this year’s draft, had his first 100-yard rushing game for Dallas, finishing with 140 yards on 30 carries.

Prescott was 19 of 24 for 248 yards in Dallas’ first home win since last year’s opener, which was a week before the first of two collarbone injuries that kept Romo out of 12 games. Romo is expected to miss about another month after breaking a bone in his back this preseason.
