The Steelers have made a change to their RB corps, signing Jawan Jamison and waving Alvester Alexander, the club announced Friday.

A 2013 seventh-round pick of Washington, the 23-year-old Jamison spent most of last season on the Redskins’ practice squad, then was promoted to the roster for the final three games. Washington waived Jamison in March.

A Rutgers product, Jamison (5-7, 203) rushed for 1,075 yards and four TDs in 2012 for the Scarlet Knights. He’ll compete to be the Steelers’ fourth back. Le’Veon Bell, LeGarrette Blount and Dri Archer will take three of the depth chart spots at tailback for Pittsburgh.

The 23-year-old Alexander is a first-year pro from Wyoming. He spent last season on the Steelers’ practice squad.
