PFT is reporting via Twitter Thursday evening that the Pittsburgh Steelers will be signing cornerback DeMarcus Van Dyke, who was waived by the Oakland Raiders just a few days ago.

Van Dyke was originally drafted by the Raider in the 3rd round of the 2011 NFL Draft after playing his college football at the University of Miami. At the 2011 NFL combine Van Dyke reportedly ran a 4.28 40-yard dash, which tied him for the third-best ever.
The speedy corneback struggled during the preseason and he was beaten twice on deep passes in the game against the Arizona Cardinals and missed a tackle on a running play that resulted in a touchdown. During his rookie season, Van Dyke played in 14 games and started 4 of them. He recorded 13 tackles, 4 passes defended and one interception.
There is no word yet what the corresponding roster move will be, but it could involve rookie right guard David DeCastro being placed on the 8 week injured reserve list.
