Bell and Miller were joined on the inactives list by kicker Shayne Graham, who was signed by the Steelers earlier this week after starting kicker Shaun Suisham was fighting through a hamstring injury.
Suisham looks to be able to play.
Cincinnati's inactives included cornerback Brandon Ghee, guard Mike Pollak, tight end Orson Charles, defensive end Margus Hunt and receiver Dane Sanzenbacher. It's the second consecutive week Hunt has been on the list of inactives.
Not listed among the Bengals' inactives for the first time this young season was left offensive tackle Andrew Whitworth. The Pro Bowl lineman missed the season opener with a knee injury suffered in preseason camp. The same knee had been operated on in the offseason, but was aggravated as Whitworth got close to making a full return in time for Week 1. He had been listed as "Questionable" on the Bengals' last injury report of the week. He is expected to start.
Earlier in the day, the Bengals waived safety Jeromy Miles. With an injured hamstring, Miles was likely to be listed on the Bengals' inactives. Linebacker J.K. Schaffer took his place on the 53-man roster. He was added from the practice squad.
Here are the full lists of inactives:
