Steelers rookie David DeCastro will miss at least half the season after suffering a knee injury in a preseason game against the Buffalo Bills on Saturday. DeCastro, the 24th pick overall in April's draft, was projected to be a starter on the offensive line for Pittsburgh, but now the team is forced to look elsewhere. The most likely replacement is Ramon Foster, a fourth-year player out of the University of Tennessee.
Foster has played in 41 games since coming to the Steelers as an undrafted free agent in 2009. He has logged 26 career starts, including 14 a season ago. He was Pittsburgh's best pass blocker in 2011, according to Steelers Depot.
