Vaughn was included on the Cowboys' initial 53-man roster following roster cuts Tuesday, Jon Machota of The Athletic reports.
Behind Tony Pollard, Dallas' situation at running back has cleared up somewhat, with Vaughn and Rico Dowdle, plus fullback Hunter Luepke, making the team over Malik Davis. With Ronald Jones suspended for the first two games of the season, Vaughn -- a 2023 sixth-round pick -- will be among the options to spell Pollard in the early going. In two preseason games, the pint-sized Vaughn became a highlight-reel favorite and notched 13 carries for 64 yards and two touchdowns, while gathering in all four of his targets for five yards.
