The Steelers signed two players, released one and saw another depart as Day 2 of free agency unfolded. It was quite busy for a team that often sits on its hands early in this market.

Veteran quarterback Bruce Gradkowski, who grew up in Dormont and played at Seton-LaSalle High School, signed a three-year contract to return home to play for the Steelers.

They later re-signed one of their own, long-snapper Greg Warren, who has spent his entire seven-year career with the Steelers.

They released Willie Colon, their starting left guard last season who spent more time nursing injuries than blocking opponents the past three years. And Rashard Mendenhall, their star-crossed No. 1 draft pick in 2008, signed a one-year contract with the Arizona Cardinals.

Gradkowski, 30, played for five NFL teams since the Tampa Bay Buccaneers drafted him in the sixth round from Toledo in 2006. He was a backup for the Cincinnati Bengals in 2012.
