William Gay is heading back to the Pittsburgh Steelers.

The veteran cornerback has agreed to a three-year deal with Pittsburgh, a move that should give the Steelers some insurance if unrestricted free agent Keenan Lewis decides to play elsewhere. Financial terms were not disclosed.

The 28-year-old Gay spent the first five seasons of his career in Pittsburgh before signing with the Arizona Cardinals last spring. Gay had two interceptions for the Cardinals.

Gay thrived while playing as a nickel back for the Steelers in 2011, finishing with two interceptions, a career-high 14 passes defensed and two fumble recoveries.

Gay didn't waste time spreading the news, changing his Twitter bio hours before the deal was officially announced.
