Dallas Cowboys owner Jerry Jones says quarterback Dak Prescott is likely to miss at least four games with a move to injured reserve because of his strained hamstring.

Dallas Cowboys quarterback Dak Prescott will have an MRI on Monday to determine the severity of a hamstring injury that forced him to leave Sunday’s loss at Atlanta.

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.
