"My guess is they'll open the season on PUP (the physically unable to perform list)," Colbert told the Pittsburgh Tribune-Review on Friday.

Kicking off 2012 on the PUP means Mendenhall would be unavailable to the Steelers until after the sixth game of the season. Colbert hinted at the same fate for nose tackle Casey Hampton ,recovering from a serious knee injury. Both players are in the final year of their contracts with the team.

"When one guy is not here,another guy steps up," Redman told NFL Network's Aditi Kinkhabwala last month . "That's Steelers football."

For many years,that's been true. Only a handful of teams in the league have shown the ability to weather roster turnover and injuries with the skill of Pittsburgh. Mendenhall has posted three straight 1,000-yard seasons,and Redman will be asked to do the same in Todd Haley's run-oriented attack. Mendenhall is often forgotten in debates about football's top young backs. He shouldn't be. Mendenhall's absence would be costly,but we expect Redman to fill the gap, because that's what this team does.
