The Eagles promoted running back Byron Marshall from the practice squad to take Wendell Smallwood's spot on the 53-man roster.

Smallwood was placed on injured reserve Monday with a knee injury. Marshall, a former Oregon standout, spent the offseason and preseason with the Eagles and has been on practice squad all year.

Darren Sproles is in the league-mandated concussion protocol, leaving the Eagles even thinner at running back. Ryan Mathews and Kenjon Barner are the top only other running backs on the roster, so Marshall could play Sunday against the Baltimore Ravens if Sproles has not recovered from the concussion.

In four preseason games, Marshall rushed 34 times for 86 yards. He also had eight catches for 60 yards. Marshall had both a 1,000-yard rushing season and 1,000-yard receiving season in college.
