The New York Giants are bringing back Steve Spagnuolo as defensive coordinator.

The 55-year-old Spagnuolo, a 34-year coaching veteran who had a failed stint as head coach of the St. Louis Rams, was a defensive assistant with the Baltimore Ravens over the past two seasons. He replaces Perry Fewell on coach Tom Coughlin's staff.

Spagnuolo helped the Giants win the 2007 Super Bowl.
