Free agent free safety Chris Crocker visited the Steelers Thursday, but left without a contract.
Crocker, a former Browns' draft pick, played in 2007 for Atlanta, recording a career-high three interceptions.
Crocker is the second free safety brought in by the Steelers for a visit this week, joining New England's Eugene Wilson.
That would seem to signal that the team was not only unhappy with Anthony Smith and Tyrone Carter at the position after Ryan Clark was lost for the season, but that it doesn't have a lot of faith that Clark will recover from his surgery to remove his spleen.
Smith, though, could be slated for a move to strong safety.
