The Steelers signed veteran offensive tackle D'Anthony Batiste today and placed rookie guard Nik Embernate on the waived/injured list.
Batiste has been with six previous NFL teams and three different leagues since 2004, when he went undrafted. He has played in the Arena and Canadian Football Leagues before joining the Dallas Cowboys in 2006.
He has played in 37 NFL games and made 14 starts.
Embernate will ultimately be placed on the Steelers' injured reserve with a season-ending knee injury that occurred Thursday in practice when two ligaments were torn, the MCL and ACL.
