quarterback Dak Prescott left Sunday's game with an apparent lower right leg injury, being replaced by veteran Andy Dalton.
In his fifth season, Prescott entered Week 5 having completed 66 percent of his passes for an NFL-high 1,690 yards along with nine touchdowns and just three interceptions. He also had 86 yards and three scores on the ground.
Despite a strong start from an individual standpoint, Prescott only managed to lead the Cowboys to one win in the first four games. And now, Dalton may have the keys to the offense moving forward.
