Rams running back Benny Cunningham (knee) is listed as active Sunday at Arizona, Myles Simmons of the Rams' official site reports.
Cunningham will take a back seat to Tre Mason and (to a greater extent) Todd Gurley, as the latter grows more accustomed to the professional game. However, as the season rolls along, Cunningham should continue to factor into the offense as a pass catcher out of the backfield.
