The Pittsburgh Steelers signed former Arizona Cardinals linebacker Markus Golden to a one-year deal on Wednesday, giving them some depth behind star running backs TJ Watt and Alex Highsmith.

Golden, 32, has spent most of his eight NFL seasons with Arizona, racking up 47 sacks in 111 games with the Cardinals and New York Giants.

Golden had 2 1/2 sacks last year for Arizona and finished with 48 tackles, tied for the third-highest total of his career.

The Steelers need help at outside linebacker after strengthening the inside linebacker in free agency by bringing in Cole Holcomb from Washington and Elandon Roberts from New England.

The Steelers are committed to keeping Highsmith, who is entering the final year of his contract, for the long term. Golden gives them some short-term depth for a team that needs experienced players to help keep Watt and Highsmith fresh later in the season.
