Just several days after they brought him in for a workout, the Steelers signed former Ohio State center Alex Stepanovich to bolster the depth on their offensive line.
Stepanovich (6-4, 296) was one of two centers who worked out last week for the Steelers after guard Darnell Stapleton had arthroscopic surgery on his left knee. Stapleton had been filling in at center because Justin Hartwig (toe) has been limited in practice and has not taken part in team drills.
He was a former fourth-round draft pick of the Arizona Cardinals in 2004 and played three seasons there before playing one season each with Cincinnati (2007) and Atlanta (2008).
Stepanovich had played in 46 NFL games, starting 34. To make room on the roster, the Steelers released defensive end Jordan Reffert.
