The Redskins liked rookie running back Keith Marshall, and the team gave the former Georgia Bulldog every chance to make the roster.
Ultimately he did not get that chance, as an elbow injury will land Marshall on the injured reserve.
Marshall sustained the injury in the team's third preseason game against the Bills. Even before the elbow injury, Marshall failed to capitalize on the opportunity to backup Matt Jones.
In games against the Jets and the Falcons, Marshall struggled to gain much ground and eventually he slid behind Robert Kelley on the team's depth chart.
For now, it appears Kelley is a lock for the Redskins 53-man roster and Marshall heads to the IR.
Scot McCloughan and the 'Skins also made two other roster moves to get the squad to the 75-man limit following this morning's release of veterans Perry Riley and Stephen Paea. Tight end Derek Carrier was moved to the Reserve/Physically Unable to Perform list and rookie WR Reggie Diggs was waived with an injured designation.
Carrier's move to the PUP list was expected, and Diggs had little chance to make the roster as an undrafted receiver even before an injury limited his training camp.
