Redman, who mentioned recently the injury won't prevent him from playing but likely will nag him throughout the season, did not play in the Steelers' 26-24 preseason win over Indianapolis Aug. 19. His return is something of a relief for the Steelers, who have had several injuries among running backs this preseason.
Rashard Mendenhall was removed from the PUP list, and has practiced lightly, but it's unlikely he'll play in either of the Steelers' remaining two preseason games. John Clay tore a quadriceps muscle, and was placed on the IR earlier in camp.
The Steelers' starters will play the first half Saturday, and Redman should get the bulk of the carries. RB Jonathan Dwyer is Redman's main back-up and has been impressive through two preseason games. How offensive coordinator Todd Haley rotates the two of them with the starting unit will be something to watch, as well as how each of them is used, both running and receiving.
