Dak Prescott’s injured hamstring is partially torn away from the bone and surgery for the star quarterback of the Dallas Cowboys is possible, a person with knowledge of the situation said Thursday.

The injury, known as a partial avulsion, is likely to lead to an absence longer than the minimum of four games that would be required by putting Prescott on injured reserve.

Potentially season-ending surgery is among the options being considered, the person told The Associated Press. The person spoke on condition of anonymity because the team hasn’t disclosed details of Prescott’s injury publicly.

In training camp two years ago, former Cowboys left tackle Tyron Smith sustained what is called a full avulsion, a complete tear of the hamstring off the bone that requires surgery, and missed 13 games.

Prescott was injured in the second half of the Cowboys’ 27-21 loss to Atlanta on Sunday. Dallas (3-5) is preparing for Cooper Rush to start multiple games, beginning Sunday at home against NFC East rival Philadelphia.

Rush went 4-1 filling in two years ago after Prescott broke the thumb on his throwing hand in a season-opening loss. He also won a game in 2021 when Prescott was out with a strained calf.

The Cowboys have made the playoffs three consecutive years with a 12-5 record, but have already matched that loss total and are three games behind Washington and the Eagles in the loss column in the NFC East.

If Prescott doesn’t return, it will be the second time in five years the 2016 AP Offensive Rookie of the Year has been sidelined most of the season. He broke an ankle in Week 5 of the 2020 season and missed 11 games.

PANTHERS’ HUBBARD GETS BIG DEAL >> The Carolina Panthers rewarded running back Chuba Hubbard with a four-year contract extension that will keep him with the team through the 2028 season.

Financial terms of the deal were not immediately available.

A 2021 fourth-round draft pick, Hubbard is in the midst of his best season with the Panthers (2-7). He is fifth in the league in yards rushing with 665 and has five touchdowns on the ground while averaging 5 yards per carry. He also has 26 receptions for 108 yards and a TD.

Hubbard ran for 72 yards and two touchdowns in Sunday’s 23-22 win over New Orleans.

Hubbard was set to become an unrestricted free agent after the season.

Next up for the Panthers for a contract extension could be cornerback Jaycee Horn, a former first-round draft pick.

The extension comes just as Panthers rookie second-round pick Jonathon Brooks is expected to make his NFL debut on Sunday in Munich against the New York Giants.
