In his weekly press conference today, Steelers head coach Mike Tomlin did not sound too confident that starting tight end Heath Miller would be ready this week against the Bengals as he recovers from the vicious concussion he sustained Sunday night against the Ravens. In fact he termed Miller doubtful today. He did give some good news injury wise and said back-up tight end Matt Spaeth has been cleared to return from his concussion he suffered against the Raiders a few weeks back. The Steelers only other tight end on the roster is David Johnson. They also have running back Isaac Redman they can use as a fullback if needed, but they would be smart to bring up either fullback Frank Summers or tight end Eugene Bright from the practice squad on Saturday to have an extra body just in case. With defensive end Brett Keisel looking like he has recovered from his hamstring and calf problems, it has made defensive tackle Steve McLendon very expendable from the roster. If waived, McLendon would likely clear waivers and could be re-signed next Monday or Tuesday. I am not saying this will indeed happen, but it does make sense and is something to look for on Saturday. The Steelers count on Spaeth and Johnson very heavily on special teams as well and it exposes them to even more to injury in the process. It would likely be in the Steelers best interest to keep him off special teams this week and replace him with either Summers or Bright or another player already on the 53 man roster.
