The Cowboys are adding a quarterback just a day after they released two from their roster. Dallas has claimed Will Grier off waivers from the Panthers. Grier was drafted in the third round of the 2019 draft by the Carolina, but was among the team's cuts on Tuesday. The quarterback started two games in 2019, but threw four interceptions and took six sacks. He'll join Cooper Rush behind Dak Prescott on the depth chart.
