Facing a critical match up vs. the Miami Dolphins at Heinz Field with an ailing offensive line, the Pittsburgh Steelers will activate tight end Matt Spaeth.

The Steelers made a surprise move in free agency to bring Spaeth, the team’s third round pick in the 2007 NFL Draft. Spaeth however suffered a lisfrac injury during training camp, and was place on the injured reserve recall list.

Spaeth reactivation comes after Heath Miller posted his best game of the season vs. the Baltimore Ravens. However, the move is more likely intended to bolster blocking efforts on an offensive line that is held together with little more than chicken wire and bubble gum.

Vs. Baltimore, the Steelers lost replacement center Fernando Velasco for the year. In addition to losing Fernando Velasco, Mike Adams, David DeCastro, and Kelvin Beachum were forced from the game with injuries. The 2013 Steelers offensive line luck has been Kafkaesque.

DeCastro will play vs. the Dolphins, and Adams will return to his spot at left tackle, where he struggled mightily during the team’s 0-4 start. Beachum is not expected to play, and third string center Cody Wallace will get his first NFL start.

To make room for Spaeth, the Steelers released Richard Gordon, who did not play but was signed as a practice body after David Johnson was lost for the year. The Steelers also have tight ends Michael Palmer and David Paulson.
