Posluszny's new deal will pay him $15 million over three seasons. The ninth-year pro was slated to earn about $7.5 million in 2015 and 2016 - what had been the final two years of a six-year, $42 million contract he signed in 2011.
Posluszny led the Jaguars in tackles in three of the last four seasons. He was on pace to do the same last year before suffering a season-ending pectoral muscle injury in Week 7.
Jaguars general manager David Caldwell says Posluszny ''is a valuable asset on and off the field and has done a great job mentoring our younger players while also performing well on the field.''
