The Steelers flip-flopped veteran inside linebackers Tuesday, releasing L.J. Fort and re-signing Steven Johnson.
It is the second time they cut and signed Johnson this year. He played in six games for them last season.
Fort, 27, played four snaps on defense in the opener in Cleveland on Sunday and 16 on special teams. He played in 14 games for them last season after briefly joining them at the end of the 2015 season. He also played for Cleveland and Seattle.
