Dallas, Texas - Dak Prescott and the Dallas Cowboys blew away the Washington Football Team with six first-half touchdowns as they recorded a comprehensive 56-14 win on Sunday.

Prescott completed 28 of 39 passes for 330 yards with four touchdowns and no interceptions, as the Cowboys reached 50 points for the first time since Super Bowl XXVII in 1993.

The Dallas QB recorded his fourth career game with 300 yards, four passing touchdowns and no interceptions, which is the most by any player in franchise history, going past Tony Romo (three). Prescott remarkably passed for 320 yards by half-time.

The Cowboys also became the first team this season to score in all three facets of the game as they dismantled Washington.

Ezekiel Elliott scored two touchdowns in the first half as the Cowboys opened up a 42-7 half-time lead. Elliott had nine carries for 37 yards and one rushing TD, along with one receiving touchdown.

Dallas had good contributions from receivers Amari Cooper (seven receptions for 85 yards and one TD) and Malik Turner (three receptions for 82 yards and one TD) and tight end Dalton Schultz (eight receptions for 82 yards and one TD).

DeMarcus Lawrence also scored a TD after intercepting Washington QB's Taylor Heinicke's first-quarter pass with Chauncey Golston cleaning up in the end zone for a touchdown after Corey Clement blocked a punt.

The Cowboys, who clinched the NFC East division earlier in the day after the Las Vegas Raiders beat the Denver Broncos 17-13, improve to 11-4 while Washington are 6-9.

Joe Burrow was in record-breaking form with the fourth most passing yards in a game in NFL history to lead the Cincinnati Bengals won 41-21 over the Baltimore Ravens, who were without Lamar Jackson.

Burrow completed 37 of 46 passes for 525 yards and four touchdowns with no interceptions, which was a new franchise record for passing yards as the Bengals claimed a major AFC North win to improve to 9-6 ahead of the 8-7 Ravens on a four-game skid.

The Bengals quarterback also becomes the fourth player in NFL history to have 500 pass yards, four pass touchdowns and zero interceptions in a game, joining Derek Carr, Ben Roethlisberger, and YA Tittle.

The Kansas City Chiefs became the first team to ever clinch the AFC West title for six straight seasons after a 36-10 win over the Pittsburgh Steelers.

Chiefs quarterback Patrick Mahomes threw 23 of 30 passes for 258 yards with three TD passes, while Steelers veteran QB Ben Roethlisberger struggled with 23 of 35 passes for 159 yards with one TD and one interception.

The Chiefs improved to an unassailable 11-4 record in the AFC West, ahead of the Los Angeles Chargers (8-4) who lost 41-29 to the Houston Texans earlier on Sunday.
