Rashard Mendenhall missed the Steelers' last game against the Tennessee Titans while he was nursing a hamstring injury. Isaac Redman started in his place and rushed for 49 yards on 15 carries. It wasn't the most impressive performance, but it was only his first career start so we're not going to hold it against him.
Now Mendenhall is back in the lineup and Redman is once again a backup. He might not prefer to give up the starting spot, but according to Mark Kaboly of the Pittsburgh Tribune, the Steelers are very comfortable with him there.
"We feel very confident when Red's in there," (Steelers offensive coordinator Bruce) Arians said. "It's all about Rashard. We don't want to get him re-injured, so it won't be an overload situation."
