This is bad news. Marcus Gilbert is suspended for 4 games for PED use by the league. Gilbert, a guard, has been one of the Steelers best lineman this season.
Gilbert has already missed time with injury and now will miss these next 4 games. He's only played in 5 games this season so far but has played well. Gilbert was a 2011 2nd round pick out of Florida and has consistently been a top offensive lineman starting even in his rookie year.
