Steelers add David DeCastro, John Malecki to 53-man roster

As the Pittsburgh Steelers continue to search for answers on offense, they did release some encouraging news on Monday afternoon. The team has added offensive guards David DeCastro and John Malecki to the 53-man roster, according to Mark Kaboly of the Pittsburgh Tribune-Review. Marcus Gilbert was placed on injured reserve, and David Gilreath was released.

DeCastro, who was selected with the 24th overall selection at the 2012 NFL Draft, is yet to play this season after sustaining a knee injury late in the preseason. He has been eligible to practice with the Steelers, although it is unclear if he will be ready for Week 13's key matchup with the Ravens. All reports indicate DeCastro has made solid progress in recent weeks, and could be a valuable asset for Pittsburgh as they make a push for the playoffs.

As for Malecki, the veteran lineman has played sparingly over the years in a backup role. He could see some playing time against the Ravens on Sunday if injuries arise.
