Former Philadelphia Eagles assistant coach Steve Spagnuolo is expected to return to his former team by the end of the week, reports the NFL Network's Jason La Canfora.
Spagnuolo, who was fired as head coach of the St. Louis Rams after three disappointing seasons, would not necessarily replace Eagles defensive coordinator Juan Castillo. It's possible Castillo could retain his position or that the team could shift him into other responsibilities to clear room for Spagnuolo, but Canfora reports that it's also possible Spagnuolo could become an "assistant head coach" in Philadelphia.
Spagnuolo spent eight years as a Philadelphia assistant under defensive coordinator Jim Johnson. He left in 2007 to become defensive coordinator for the New York Giants, where he was architect of the high-octane defense that stunned New England in the Super Bowl. He ultimately left the Giants to join the Rams, but won just 10 games in three seasons and was let go after this season.
