During the NFL preseason, Darius Jackson and Bo Scarbrough were thought to be competing for the No. 3 running-back job behind starter Ezekiel Elliott and Rod Smith. But when the Cowboys trimmed their 90-player preseason roster to the regular-season limit of 53, neither Jackson nor Scarbrough made the team.
Dallas did pick up Jackson for its practice squad, but he stayed there only briefly before being signed away by the Green Bay Packers. The Cowboys signed Scarbrough to fill the vacancy on the practice squad.
Jackson had appeared in two games this season for Green Bay, getting on the field for 20 special-teams plays. A sixth-round selection of the Cowboys in the 2016 NFL Draft, those two games are the only regular-season appearances of Jackson’s career.
Scarbrough joined Dallas as a seventh-round draft pick from Alabama in April.
In the Cowboys’ four preseason games, Scarbrough ran for 69 yards and one touchdown on 24 carries, with 28 of the yards coming on one run in the first game. He also caught four passes for 33 yards as he dealt with a hip injury in training camp.
