The Green Bay Packers have filled their vacancy at defensive coordinator with former Arizona Cardinals head coach Jonathan Gannon, according to multiple reports.Jonathan Gannon was fired by the Cardinals on Jan. 5, following a disappointing 3-14 season, his third and final year with the team. He finished with a record of 15-36 with the Cardinals.Gannon joins the Packers’ staff after the departure of former defensive coordinator Jeff Hafley, who was hired as the Miami Dolphins’ new head coach. The Packers were the NFC’s No. 7 seed in this year’s playoffs after finishing the 2025 season with a 9-7-1 record.
Gannon interviewed twice for the job this week, positioning himself as a favorite for the position. Instead of waiting through the weekend to make the hire, which might have given LaFleur a chance to speak with Denver Broncos defensive passing game coordinator and former Wisconsin defensive coordinator Jim Leonhard, the Packers closed the position swiftly.
Before getting his shot at being an NFL head coach, Gannon was the Philadelphia Eagles defensive coordinator for two seasons, including their Super Bowl run in 2022. Gannon rose through the coaching ranks as a defensive backs coach, working with the Indianapolis Colts and Minnesota Vikings before arriving in Philadelphia.
Gannon will have a chance to rehabilitate his future head-coaching prospects with a Packers defense stacked on talent, starting with Micah Parsons.
