With Andre Ellington not making the trip to Chicago, the Arizona Cardinals made a roster move at running back.
The team announced it promoted running back Kerwynn Williams from the practice squad in advance of Sunday's game against the Bears.
Chris Johnson is set to get the start, with rookie David Johnson getting a slight increase as a pass-catcher out of the backfield.
Coach Bruce Arians said this week if the Cardinals hadn't signed Chris Johnson during training camp, they would have turned to Williams as the starter with Ellington out.
"If we didn't have Chris we'd probably turn to Kerwynn because he's done it before, and keep David in his role," Arians said, via the team's official website. "(David Johnson's) role has expanded (this week) and it should expand every week now."
David Johnson flashed his speed on a 55-yard touchdown catch to seal the Week 1 victory for the Cardinals over the New Orleans Saints. The rookie played just five snaps and had no carries.
Williams earned 246 yards on 53 carries (4.6 average) in five games last season with the Cards.
Arizona cut tight end Joseph Fauria to make room on the active roster. The Cardinals signed Fauria prior to last week's contest.
