Vaughn carried the ball five times for 34 yards in Saturday's preseason game against the Raiders. He also returned one kickoff for 25 yards.
The undersized back looked good in his first exhibition action after missing the Cowboys' preseason opener due to a hamstring injury. Vaughn led all Dallas backs in rushing yards and showed some surprising power through contact in addition to his usual elusiveness. The 2023 sixth-round pick is fighting for a depth spot behind Ezekiel Elliott and Rico Dowdle in the backfield, and his ability to contribute on special teams could help him secure a spot on the game-day roster.
