The Cowboys lost Dak Prescott to a hamstring injury in the fourth quarter against the Atlanta Falcons.
Backup quarterback Cooper Rush entered in his place.
Prescott had rushed three times for 30 yards in the game, plus a fourth scramble that was called back due to a holding penalty.
He rushed twice on the drive before he went out.
While the Cowboys officially ruled him out with a hamstring injury following evaluation in the blue medical tent, Prescott’s throwing hand also swelled early in the fourth quarter. Medical staff tended to a wound at the base of his right pinky finger.
The Cowboys trailed 27-13 as Rush went in.
Prescott completed 18 of 24 passes for 133 yards and a touchdown in addition to his 30 rushing yards.
Wide receiver CeeDee Lamb was also ruled questionable to return with a late shoulder injury he suffered.
