Looking to add some depth to their secondary, the Pittsburgh Steelers are expected to sign cornerback DeMarcus Van Dyke, according to a report by ProFootballTalk (via Steelers Depot).
Van Dyke was most recently with the Oakland Raiders, the team that drafted him in the third round in 2011, but was waived a few days ago after a shaky preseason.
Coming out of the University of Miami (FL), Van Dyke reportedly posted a 4.28 40-yard dash time, the fastest clocked at the 2011 NFL Draft Combine. He played in 14 games last season for the Raiders, starting in four of them and tallying 13 total tackles, four passes defended and one interception.
The signing of Van Dyke could indicate that Steelers rookie right guard David DeCastro will be heading to the eight week injured reserve list, according to the report, after suffering a knee injury in Pittsburgh's preseason victory over the Buffalo Bills on Aug. 25.
