We heard last week that longtime Eagles DT Fletcher Cox was widely expected to retire. Cox is following through on that decision, announcing on his Instagram page that he is hanging up the cleats (via Mike Garafolo of the NFL Network). 
Cox, 33, joins center Jason Kelce as a member of Philadelphia’s storied ‘Core Four’ who will not be in place moving forward. Cox will end his Eagles tenure ranked third in franchise history in games played behind only Kelce and defensive end Brandon Graham. The latter is working on a new deal, but Cox’s absence will still leave a major vacancy along the defensive line.
The former first-rounder spent his entire 12-year career in Philadelphia, although in recent seasons he faced a relatively uncertain future. Cox was released in 2022 before re-joining the team on a less expensive contract. The following year, he fielded outside offers before electing to sign another one-year pact with the Eagles. Cox turned down more money in doing so, and over the course of the 2023 campaign he remained a full-time starter along the interior.
The Mississippi State alum notched five sacks last season, adding to his consistent production in that regard throughout his decorated career. Cox reached the double-digit sack mark only once (in 2018), but he was a Pro Bowler six consecutive times in a stretch from 2015-20. He earned second-team All-Pro honors three times, along with a first-team inclusion in 2018. Cox’s decorated resume includes a spot on the 2010s All-Decade team.
A major contributor to the Eagles’ Super Bowl-winning team in 2017 as well as the one which reached the title game in 2022, Cox will leave the game with a championship ring and a reputation as one of the top defensive linemen of his generation. Replacing him will be a tall order, though the Eagles have prepared for this news in recent offseasons by selecting Jordan Davis and Jalen Carter in the first round of the past two drafts. That duo will face increased expectations in 2024 and beyond.
“I gave everything I had to this team and to this city,” Cox’s announcement reads in part. “I don’t know what’s next for me, but I do know that I’m forever grateful for my time here in Philadelphia and with the Eagles organization.”
Cox continued to land eight-figure deals after the conclusion of his rookie pact, highlighted by his 2016 extension. That six-year, $102.6MM deal allowed him to build much of his illustrious Philadelphia tenure while adding considerably to his financial success in the NFL. In all, Cox will depart with more than $128MM in career earnings.
