Cardinals promote RB Kerwynn Williams from practice squad

The Cardinals have promoted running back Kerwynn Williams from their practice squad to the team's active roster in advance of Week 2.

With Andre Ellington injured, Williams will bolster the Cards' backfield depth, though as it stands now he figures to slot in behind both Chris Johnson and David Johnson in the team's running back pecking order, with Stepfan Taylor also in the mix on that front.
