Packers president Mark Murphy last week said extending Thompson's and McCarthy's deals, which were scheduled to expire in 2012, was a priority following Sunday's 31-25 victory over the Pittsburgh Steelers in Super Bowl XLV.
"This is a great organization, and I am very humbled and appreciative," Thompson said in a statement released by the team. "Green Bay is a special place, and I am honored to work with such a great group of people that have all contributed to our success."
Murphy said Friday the organization is thrilled to keep Thompson, 58, after working on and reaching an agreement on a new contract in December. The terms of the deal weren't disclosed.
Of Green Bay's 53 active players against Pittsburgh, 49 were acquired by Thompson, 26 through the draft.
