Jenkins signed a five-year, $25 million contract last offseason and recorded 5.5 sacks, seven tackles for loss, and 61 total tackles during his first season with the Eagles. He spent his first seven seasons with Green Bay.
"We are very excited about having Cullen back on our football team," Eagles general manager Howie Roseman said Tuesday. "Cullen made an immediate impact for us this year on and off the field. We look forward to a great future together with him in an Eagles uniform."
Jenkins said during a conference call Tuesday that security was one of his motivating factors in getting a deal done.
"I wanted to have something where it would be a lot more realistic to move forward in the long term and I think we were able to accomplish that," He said, per the team's official website. "I wanted to be able to retire an Eagle. I want to be able to retire out here and finish my career as an Eagle. That was something we took into consideration."
The Eagles went 8-8 last season.
