A second-round pick from Michigan State, Bell has missed the first two regular-season games with a foot injury suffered in Pittsburgh’s second preseason game.
The Steelers are 31st in rushing yards entering Week Three.
Five Steelers are listed as probable on the injury report, including tight end Heath Miller, who was a full practice participant for a third straight day. He appears set to make his 2013 debut after suffering a torn ACL late last season. Rookie outside linebacker Jarvis Jones (heel) is also probable after his first full practice of the week.
