Jalen Carter's Shoulder Issues Could Derail His Massive Extension
Jalen Carter ranked 115th of 130 in run defense last season because he couldn't lift weights due to chronic shoulder pain. Now his contract extension talks just got a lot more complicated.
Jalen Carter's Shoulder Issues Could Derail His Massive Extension
The Philadelphia Eagles may have a bigger problem on their hands than the AJ Brown trade drama or the NFL Draft — and it starts with Jalen Carter's shoulders.
As discussed on Birds 365, Carter dealt with persistent pain in both shoulders throughout the 2024 season. Not a one-time injury. Not a tweak. Ongoing, chronic pain in both rotator cuffs that fundamentally changed how he played football. And the ripple effects could reshape the Eagles' entire defensive future.
The Numbers Tell the Story
Carter's run defense fell off a cliff last season. He ranked 115th out of 130 defensive tackles in run defense, getting blown off the ball consistently by offensive linemen who had no business moving him. For a player who was supposed to anchor the Eagles' defensive line for the next decade, those numbers are alarming.
For context, his pass rush remained elite — 13th out of 112 — which tells you everything about what the shoulders specifically affected. Pass rushing relies on speed, technique, and leverage at the point of attack. Run defense requires absorbing 300-pound offensive linemen driving into your chest. When your shoulders can't handle that force, you get moved. And Carter got moved all season.
He couldn't lift weights. Let that sink in. An NFL defensive tackle who couldn't lift weights tried to stop the run against professional offensive linemen. The results were predictable. Every double team became a win for the offense. Every gap assignment became a liability.
PRP Therapy and the Road Forward
The Eagles are banking on PRP therapy — platelet-rich plasma injections — the same treatment they've used with Cam Juergens and Saquon Barkley to manage chronic pain. Jeffrey Lurie himself referenced it when discussing Carter's recovery plan, suggesting the organization is taking the shoulder situation seriously at the highest levels.
But shoulders are different from knees or ankles. They're unpredictable, persistent, and potentially career-altering if they don't respond to treatment. The comparison to other players who've dealt with similar issues isn't encouraging. Persistent shoulder pain in both rotator cuffs can limit range of motion, reduce power output, and create compensatory movement patterns that lead to other injuries.
The good news: Carter is 24 years old. His body has time to respond to treatment. The Eagles' medical staff has a track record of managing these situations. But there are no guarantees, and the timeline for a full return to his 2023 dominance is unclear.
What This Means for the Contract
Carter's extension negotiations just got significantly more complicated. The Eagles want to lock up their franchise defensive tackle long-term. Carter wants maximum money — the kind of deal that would make him one of the highest-paid interior defenders in football. But both sides know the shoulders change the calculus entirely.
Carter might want to bet on himself with a prove-it season — but when you're talking about $25-30 million per year, the risk calculation shifts dramatically. The Eagles, meanwhile, have to weigh paying top-five money for a player whose durability is genuinely uncertain.
The draft complicates things further. With the 23rd pick just 17 days away, the Eagles have to consider whether they need a defensive tackle earlier than planned. Not as a replacement — nobody replaces Jalen Carter — but as insurance. If the shoulders don't cooperate, having a capable rotational piece becomes essential rather than optional. Howie Roseman doesn't make moves out of panic, but he does make moves out of preparation. And right now, the Carter situation demands preparation for every scenario.
If the shoulders respond to treatment and Carter returns to his dominant 2023 form, Howie Roseman writes the check without hesitation. If they don't — if Carter is still getting moved in the run game next October — this becomes one of the most difficult decisions of Roseman's tenure. And at 17 days from the draft, the Eagles might be thinking about defensive tackle insurance earlier than anyone expected.
