Chris Rainey's arrest Thursday was the latest issue in what has been a rough rookie season for the Steelers' 2012 draft class:
First round: David DeCastro, G, Stanford. Severely injured his knee in the third preseason game and returned to play the last three games.
Second round: Mike Adams, OT, Ohio State. Placed on injured reserve with an ankle injury after starting six games.
Third round: Sean Spence, ILB, Miami. Tore multiple ligaments in his left knee in preseason finale and placed on injured reserve before regular season started.
Fourth round: Alameda Ta'amu, NT, Washington. Arrested for drunken driving in October, which led to his release a month later. He was later re-signed.
Fifth round: Chris Rainey, RB, Florida. Arrested for simple battery Thursday. He had 162 total yards and two touchdowns as a rookie. (4:12 p.m. ET update: The Steelers have waived Rainey.)
Seventh round: Toney Clemons, WR, Colorado. Signed off Steelers' practice squad by the Jaguars in November.
Seventh round: David Paulson, TE, Oregon. Finished with seven catches for 51 yards in 16 games played for Steelers.
Seventh round: Terrence Frederick, CB, Texas A&M. Waived by the Steelers at the end of the preseason and was later signed by the Giants.
