Vaughn didn't see a touch and got only three snaps on offense in Thursday's win over the Giants.
The 2023 sixth-round pick continues to be a distant third in the Dallas backfield hierarchy behind Rico Dowdle and Ezekiel Elliott, and Vaughn failed to touch the ball in Week 4 for the first time all season. With Dalvin Cook stashed on the practice squad and the Cowboys getting little production from their running game, Vaughn's hold on a 53-man roster spot appears tenuous at best.
