The Buffalo Bills showcased their dominance in the first half of their game against the Dallas Cowboys, taking a commanding 21-3 lead. The Bills' offense, led by quarterback Josh Allen, orchestrated an impressive 11-play drive that culminated in a one-yard rushing score by Allen himself on a quarterback sneak.

Running back James Cook proved to be a formidable force for the Bills, already accumulating over 100 yards rushing on 15 carries. Cook's exceptional performance boasted an impressive average of 6.9 yards per carry, leaving the Cowboys struggling to contain him. The absence of starting defensive tackle Johnathan Hankins due to knee and ankle injuries was evident for the Cowboys, as they failed to halt the Bills' offensive prowess.

However, both teams faced setbacks due to injuries. Cowboys safety Donovan Wilson and linebacker Damone Clark suffered injuries on consecutive plays, leading to concerns about their availability moving forward in the game.

A potential turnover opportunity arose for the Cowboys when it seemed that Bills wide receiver Stefon Diggs had fumbled on the previous play. Surprisingly, Cowboys head coach Mike McCarthy decided not to challenge the call, allowing the Bills to maintain possession. The Bills capitalized on this opportunity and advanced further downfield after a penalty on Cowboys safety Jayron Kearse for unnecessary roughness.

The Cowboys managed to put points on the board when rookie kicker Brandon Aubrey successfully connected on a 32-yard field goal. This came after a stalled drive, highlighted by a loss of three yards on a run by Tony Pollard and a deflected pass by Dak Prescott, forcing a third down stop. Despite this, the Bills maintained a comfortable 14-3 lead.

The Bills continued to capitalize on penalties committed by the Cowboys, as linebacker Tyrel Dodson was penalized for unnecessary roughness on Cowboys quarterback Dak Prescott, resulting in a first down for Dallas near midfield.

Following a series of successful drives, the Bills extended their lead with an 18-yard touchdown pass from Allen to Cook, who found himself wide open in the corner of the end zone. The scoreboard now displayed a dominant 14-0 lead for the Bills with 12:52 remaining in the first half.

Another crucial penalty extended the Bills' drive, as Cowboys defensive lineman Sam Williams collided with Bills punter Sam Martin, resulting in a roughing the kicker penalty. This was the second time the Bills benefited from a penalty extending their drive, the first being a roughing the passer call on DeMarcus Lawrence near the goal line. The Bills capitalized on these opportunities, converting them into touchdowns and asserting their dominance on the field.

Despite Cowboys right guard Zack Martin leaving the field after colliding with left tackle Tyron Smith, the Cowboys offense struggled to find their rhythm. Three consecutive incomplete passes by Prescott forced a three-and-out, granting the Bills another chance to extend their lead.

The Cowboys' defense showed resilience, forcing a three-and-out after their offense failed to produce on the opening drive. However, the Cowboys were plagued by penalties, with left guard Tyler Smith's holding infraction resulting in a combined loss of 11 yards for the team. This hindered their progress, and the Cowboys were forced to punt.

The game intensified with heated emotions as penalties were called on both teams after the play's conclusion. Bills safety Taylor Rapp was called for unnecessary roughness on a hit against Prescott, while Cowboys right guard Zack Martin was penalized for unnecessary roughness after shoving a Bills player following the play.

The Bills capitalized on a roughing the passer penalty committed by Cowboys defensive end DeMarcus Lawrence, converting their second chance into a touchdown. Running back Latavius Murray rushed for a two-yard touchdown, extending the Bills' lead to 7-0 in the opening drive.

As the second half approaches, the Bills maintain a substantial lead over the Cowboys, displaying exceptional offensive performances and capitalizing on penalties. The Cowboys will need to regroup and develop a stronger strategy to mount a comeback and close the gap on the scoreboard.
