Carter, a six-year NFL veteran, was signed by the Steelers Oct. 20 of last season after veteran safety Mike Logan was placed on injured reserve with a hamstring injury. Carter played in 12 games for the Steelers, including the postseason, recording seven special teams tackles.
Carter was originally drafted by the Minnesota Vikings in 2000, spending three seasons with the Vikings. He played in 2003 for the New York Jets, starting at free safety. In 62 career games, Carter has 31 starts. He has recorded 230 tackles, three interceptions and one sack.
The 5-8, 190-pound Carter will compete with Logan and Russell Stuvaints for a job backing up starting safeties Chris Hope and Troy Polamalu. Hope is a restricted free agent and has yet to sign the Steelers tender offer to him.
Carter joins cornerback Willie Williams and offensive lineman Barrett Brooks as unrestricted free agents to re-sign with the Steelers this offseason.
