ARLINGTON, Texas (AP) — DaRon Bland set an NFL record with his fifth interception return for a touchdown this season, Dak Prescott threw four TD passes and Dallas defeated Washington 45-10 in a battle between the two NFL East division rivals late Thursday afternoon.

The Cowboys (8-3) extended their longest home winning streak in 42 years to 13 games. Dallas won 18 in a row at home from 1979-81.

Dallas led by less than two TDs going into the fourth quarter for the first time in five home games this season. The Cowboys ended up tying a 55-year-old franchise record with a seventh victory by at least 20 points this season.

Sam Howell threw for 300 yards and had a rushing touchdown, but was sacked at his 24-yard line on fourth down early in the fourth quarter, setting up CeeDee Lamb’s touchdown and 2-point conversion catches for a 21-point Dallas lead.

Washington (4-8) lost for the eighth time in 10 games.

Prescott threw for 331 yards in his fifth consecutive game with at least two TD passes. Rico Dowdle, Brandin Cooks and KaVontae Turpin had the other scoring grabs.

49ERS 31, SEAHAWKS 13

SEATTLE (AP) — Christian McCaffrey rushed for 114 yards and two touchdowns in the first half, and NFC West-leading San Francisco built a 21-point lead by halftime in rolling past Seattle.

The 49ers (8-3) won their fourth straight against their division rivals and have a two-game lead over Seattle in the division. San Francisco won its third straight following a three-game losing streak and picked up its 10th straight win against an NFC West opponent.

McCaffrey rushed for touchdowns of 8 and 1 yards as the 49ers built a 24-3 halftime advantage. Deebo Samuel also ran for a 2-yard touchdown on San Francisco’s opening possession and Brock Purdy was nearly flawless in the first half, completing 15 of 20 passes.

Purdy threw an interception that was returned for a touchdown early in the third quarter. He finished 21 of 30 for 209 yards.

Seattle’s Geno Smith was playing banged up after leaving last Sunday’s loss to the Los Angeles Rams in the second half with an injury in his right arm, near his elbow. He was 18 of 27 for 180 yards. He was sacked six times, threw an interception in the first half and nearly had a few more throws picked off.

The Seahawks (6-5) gained 15 total yards on their first five possessions.
