ARLINGTON, Texas (AP) — Dak Prescott joined both his tackles and his tight end on the list of season-ending injuries for the Dallas offense when the star quarterback fractured his ankle in a gruesome scene against the New York Giants.

The emotional setback added to the challenge of trying to make the playoffs in coach Mike McCarthy’s first season, although the rally for a 37-34 victory behind backup Andy Dalton vaulted the Cowboys (2-3) to first place in the struggling NFC East.

“I know how much this means to him and how much being out there for this team means for him,” running back Ezekiel Elliott said of Prescott. “So, it’s hard. But all we can do right now is support him. We just gotta support ‘4’ and make sure he is good, and go out there and win ballgames for him.”

Prescott had surgery for a compound fracture and dislocation of his right ankle and the team said he was expected to be released from a hospital Monday. The two-time Pro Bowler’s lower leg got caught under New York defensive back Logan Ryan on a tackle at the end of a 9-yard run.

Left tackle Tyron Smith is out for the year with a neck issue after playing just two games, and right tackle La’el Collins never saw the field before needing season-ending hip surgery. Tight end Blake Jarwin tore a knee ligament in the opener.

The Dallas defense has been plagued by injuries as well, the latest being defensive tackle Trysten Hill’s season-ending knee injury against the Giants.

The Cowboys, who play Arizona at home next Monday night, have been without Leighton Vander Esch for a month after the middle linebacker broke a collarbone in the opener. Defensive tackle Gerald McCoy sustained a season-ending leg injury in training camp.

Cornerback Anthony Brown returned after missing the minimum three games on injured reserve with a rib issue and returned a fumble for a touchdown. Another starting cornerback, Chidobe Awuzie, is out with a groin injury.

There are also plenty of self-inflicted reasons for the rollercoaster ride, from turnovers to mistakes on special teams to plenty of blown assignments for a defense trying to learn a new scheme.

“If you look at the five games that we’ve played in, we’ve had some rough moments, but every game has come down to the end,” McCarthy said. “There are still some things that we can sync up better and I think it allows everybody to perform at a faster level. We’re going to have to make some adjustments moving forward.”
