PITTSBURGH (AP) — The Pittsburgh Steelers have released veteran quarterback Troy Smith, a former Ohio State star who won the 2006 Heisman Trophy.

Smith signed with the Steelers earlier this year. He has also spent time with the Omaha Nighthawks (2011) of the United Football League, the San Francisco 49ers (2010) and the Baltimore Ravens (2007-2009). The Ravens drafted him in the fifth round (174th overall) of the 2007 draft.

Smith played in 20 NFL games with eight career starts.

He led Ohio State to a 12-0 record and the No. 1 ranking in 2006 before the Buckeyes were beaten 41-14 by Florida in the Bowl Championship Series title game in Glendale, Ariz. Smith threw 54 TD passes in his career, third best at Ohio State.
