Through Wednesday, the Steelers haven't made any roster changes, meaning, as of now, the Steelers intend to keep 10 defensive backs heading into Sunday's Week 2 game vs. the Jets.
With Ryan Clark's return to the lineup, it was thought a move could be made to release either veteran safety Will Allen or rookie S Robert Golden, but nothing on that front has been confirmed.
The Steelers also added cornerback DeMarcus Van Dyke before Week 1, and Van Dyke saw a few snaps on special teams in that game.
Van Dyke was added when the Steelers placed offensive guard David DeCastro on injured-reserve with a designation to return after Week 8. The Steelers have not confirmed where Van Dyke sits on the depth chart yet.
Those four, along with Ryan Mundy, Troy Polamalu, Ike Taylor, Keenan Lewis, Cortez Allen and Curtis Brown make up the Steelers' secondary.
There's no law against keeping 10 defensive backs (five safeties and five corners) but it's not typical.
The pending absence of linebackers James Harrison (knee) and Stevenson Sylvester (knee) could be part of the reason rookie Adrian Robinson made the roster in the first place, but now, considering the Van Dyke signing, it doesn't look like he's going anywhere. Robinson saw very limited snaps on special teams in Week 1.
Despite Steelers coach Mike Tomlin saying before Week 1 rookie running back Chris Rainey would be his return man, that did not happen. Antonio Brown returned punts and Emmanuel Sanders returned kicks.
Projected Inactives (as of Wednesday):
QB Charlie Batch, NT Alamed Ta'amu, RB Rashard Mendenhall, OL Kelvin Beachum, LB Stevenson Sylvester, either James Harrison or Adrian Robinson, either Robert Golden or DeMarcus Van Dyke
