Dallas Cowboys quarterback Dak Prescott left Sunday’s game against the Atlanta Falcons in the fourth quarter with a hamstring injury. He was replaced by backup quarterback Cooper Rush.

Prescott was taken out with the Cowboys trailing 27-13. He had completed 18 of 24 passes for 133 yards and one touchdown before his day ended.

Dallas entered Sunday’s matchup with the Falcons with a 3-4 record. The Cowboys were 3-2 before a two-game losing streak headed into Week 9.

Prescott has struggled so far this season, throwing for 11 touchdowns and eight interceptions through Sunday’s game.

His 84.5 passer rating through seven games is the worst mark of his career, as is his quarterback rating of 47.5. Prescott’s completion percentage and yards per attempt average entering Week 9 are the second-lowest marks of his career.

In September, Prescott signed a four-year, $240 million contract that made him the highest-paid player in NFL history, according to multiple reports. The deal includes $231 million in guaranteed money.

Rush, 30, spent the first three years of his career with the Cowboys. He played for the New York Giants in 2020 before rejoining Dallas in 2021.

Rush saw his most extensive playing time in the 2022 season, starting five games in place of an injured Prescott. He went 4-1 in those games.

In his career before Sunday, Rush completed 60.8% of his passes for 1,671 yards with eight touchdowns and six interceptions.

The Cowboys, who are in third place in the NFC East, play their divisional rival Philadelphia Eagles in Week 10.
