Cowboys QB depth chart: Cooper Rush to start, Trey Lance new No. 2 after Dak Prescott injury
Rush went to Central Michigan from 2012-2016. He went undrafted in the 2017 NFL Draft and signed with the Cowboys as an undrafted free agent. Rush was with Dallas for three years but then was claimed by the New York Giants off waivers in 2020. They added him to their practice squad but then released him in late September.
