PITTSBURGH (AP) -- The Pittsburgh Steelers have signed 2006 Heisman Trophy quarterback Troy Smith to a reserve/futures contract.
Smith spent three seasons with the Baltimore Ravens from 2007-09, beating the Steelers as a rookie starter in 2007. He was with the San Francisco 49ers in 2010. He last played with the Omaha Nighthawks of the United Football League.
Pittsburgh quarterbacks Byron Leftwich and Charlie Batch will become unrestricted free agents in the offseason, and Smith gives the team depth heading into mini-camp and organized team activities.
The Steelers also signed cornerback Walter McFadden, who played for the Oakland Raiders in 2010 and split his time between the Raiders and the Cincinnati Bengals in 2011.
Pittsburgh also signed wide receivers Tyler Beiler, David Gilreath, Derrick Williams and Jimmy Young.
