Dalvin Cook is set to make his debut with the Dallas Cowboys this Sunday against the San Francisco 49ers. After being signed to the practice squad prior to the season, Cook's opportunity comes as the Cowboys struggle with the league's worst rushing average.

Coach Mike McCarthy has indicated that Cook is ready to contribute. Despite a challenging previous season with the New York Jets, where he totaled just 214 yards, Cook's elevation raises questions about the team's running back lineup for the game.
