Steelers Sign CB DeMarcus Van Dyke

Jerry Dulac of the Post-Gazette reports that the Steelers have signed CB DeMarcus Van Dyke after having him in for a workout this morning. DVD spent time on the roster last year, and saw mostly limited snaps on special teams, during a  handful of games.  He was with the team in training camp this summer, but suffered a serious hamstring injury during the last week of July. Van Dyke is a speedster, who ran a 4.28 40 yd during his 2011 combine.  Bringing in Van Dyke is a depth move as Ike Taylor is recovering from concussion symptoms this week.
