GREEN BAY, Wis. (CBS 58) -- The Green Bay Packers and defensive coordinator Mike Pettine appear to be parting ways.

Several reports say Pettine will not return to Green Bay. His contract expired after this past season.

Pettine spent the last three seasons as the Packers defensive coordinator. Green Bay’s defense gave up 31 points to Tampa Bay in Sunday’s NFC Championship Game, making several key mistakes including a pass interference which gave the Buccaneers a game-clinching first down.

Pettine has also been the defensive coordinator for the Jets and Bills, and he was the head coach of the Cleveland Browns for two seasons.
