Although agent Jerrold Colton declined to say if his client has signed a contract with the Steelers, Gay, 28, identifies himself on his Twitter account as a "cornerback of the Pittsburgh Steelers."
Gay was a Steelers' cornerback in 2009, lost his job to Bryant McFadden in 2010, regained it in 2011 and signed with Arizona as a free agent in 2012, with Keenan Lewis taking his place in Pittsburgh.
The Steelers may lose Lewis to unrestricted free agency, the Pittsburgh Post-Gazette said Monday.
