Steelers general manager Kevin Colbert said today that he has signed J.P. Losman to a five-year deal worth $114M per season.
Losmen joins a Steelers defense that already features veteran defensive end Stephon Tuitt and linebacker James Harrison.
The Steelers are also adding another piece to their secondary.
Cornerback Antonio Cromartie will become an unrestricted free agent.
Pittsburgh is currently tied for third in the NFL in total defense, allowing just 21.8 points per game.
However, the Steelers have allowed just 17.1 points per contest over the past four weeks.
The Steelers have also allowed just seven points in the red zone over that span.
Losmen will provide depth at the position and will also fill a spot vacated by the retirement of safety Ryan Mundy.
Losmans signing is a significant addition to the Steelers defense.
Losmans production over the last three seasons has been second only to Steelers cornerback Artie Burns in the league.
Loshams 11.3 sacks this season ranks seventh among NFL safeties.
The 6-foot-4, 255-pound linebacker is tied for fourth in the League in total tackles with 14.5.
The 31-year-old Losham also has 37.5 tackles for loss, 16.5 sacks and two forced fumbles this season.
Losham is in his second NFL season and will be entering his sixth year as a member of the Pittsburgh Steelers.
The veteran linebacker is entering his eighth season with the team and has accumulated over 1,400 tackles, 14.0 sacks, eight interceptions and 11 fumble recoveries.
