Dak Prescott's preseason is over after four drives in three games. Since the Cowboys do not play their starters in the final preseason game, Prescott will enter the Sept. 8 opener having completed 11 of 14 passes for 109 yards and a touchdown. He had his first three incompletions of the preseason against Houston but his touchdown pass to Michael Gallup, which was for 12 yards, was typical Prescott. He scrambled, fought through a tackler and found Gallup in the end zone.
