Kelley is listed as the No. 3 back on Washington's initial regular-season depth chart.
Kelley, an undrafted rookie free agent, found his way onto Washington's 53-man roster, beating out Mack Brown for the No. 3 spot in the backfield. With both Matt Jones (shoulder) and Chris Thompson (shoulder) nursing injuries this week, it's possible that Kelley could see the field in Week 1's tilt with the Steelers on Monday night.
