The hamstring injury sustained by Dallas Cowboys quarterback Dak Prescott is worse than originally thought, likely sidelining him for several weeks, NFL Network and ESPN reported Monday.

Prescott is seeking a second opinion on his options, per the reports.

Prescott was injured in Sunday’s 27-21 loss to the Atlanta Falcons.

With Dallas (3-5) down 27-13 near the end of the third quarter, Prescott appeared to grimace after a 10-yard pass to Jalen Brooks. He stayed in the game but was ruled out with 11:08 left in the fourth quarter. Prescott said he first felt the pain the play before the completion to Brooks, when he was getting up after a 5-yard scramble.

Cooper Rush, who replaced Prescott on Sunday, is in line to start. Trey Lance would be his backup.

Making his 36th straight start, Prescott was 18-of-24 passing for 133 yards and a touchdown, along with a season-high 30 rushing yards. The 31-year-old entered the day with 24 rushing yards this season.

Rush led Dallas’ comeback bid, tossing for 115 yards and a touchdown. Rush has played sparingly of late behind Prescott, but after the longtime starting QB broke his right thumb in the 2022 season opener, Rush went 4-1 as the starter.

Prescott also missed 11 games in 2020 with a right ankle injury and sat out one game the next season due to a strained right calf.
