The Dallas Cowboys were overmatched in their Week 9 game against the Atlanta Falcons, a 27-21 defeat. And that was before losing quarterback Dak Prescott for the bulk of the fourth quarter due to a hamstring injury.

Dallas Cowboys quarterback Dak Prescott will miss at least one game with a hamstring injury that the team says is still being evaluated.

Prescott went in the injury tent with team trainers following Dallas’ field goal drive at the end of the third quarter. Trainers were also seen examining Prescott’s bloodied hand during the ensuing Falcons drive. The Cowboys quarterback returned to the sideline after six minutes, remaining in his uniform, but did not return to the game.
