As the Steelers keep losing players — three starters in their season opener alone — it doesn't appear as if they're ready yet to welcome back two key starters.

Tight end Heath Miller will return to team work this week for the first time since late last season but coach Mike Tomlin still isn't sure when he will return. Miller tore two knee ligaments and badly injured a third during the Bengals game on Dec. 23 and has yet to practice fully since then.

On his weekly radio show quarterback Ben Roethlisberger said one issue with Miller is how he responds following workouts — suggesting he continues to deal with swelling in the knee some days.

Running back Le'Veon Bell (mid-foot sprain) said last week he hoped to return as early as the Monday night game in Cincinnati but Tomlin said Tuesday he has no update on his status. Bell was expected to miss as much as the first month of the season.

Without Bell who would have been the season-opening starter the Steelers ran for only 32 yards during their 16-9 loss to the Titans on Sunday. Tomlin said that “as miserable as it was” there were some positives to come out of the team's third consecutive season-opening loss.

On the depth chart rookie Jarvis Jones is listed as the co-starter at outside linebacker along with Jason Worilds. Worilds played slightly more against the Titans.

Isaac Redman is listed as the co-starter at running back with Bell with the newly returned Jonathan Dwyer ahead of Felix Jones. Jones had two strong preseason performances after being picked up from the Eagles in a trade but Tomlin said his lack of experience with the Steelers' offense prevented him from playing more against Tennessee.

Dwyer was released during the final roster cutdown Aug. 31 but returned Monday. He ran for 122 yards on 17 carries as the Steelers beat the Bengals 24-17 in Cincinnati last season when Pouncey also was out with an injury.

While the Steelers added kicker Shayne Graham on Monday Tomlin said Shaun Suisham's hamstring injury does not appear to be serious and he could kick against the Bengals.
