J.J. McCarthy Undergoes Meniscus Surgery, To Miss 2024 Season

The Vikings did not look to be planning to start J.J. McCarthy to open the season, but their design of an extended onramp will change. After Tuesday’s news of the rookie quarterback’s meniscus injury, today’s surgery will entrench Sam Darnold atop Minnesota’s depth chart.

McCarthy underwent a full meniscus repair, according to NFL.com’s Ian Rapoport and Tom Pelissero. As a result, the No. 10 overall pick will miss the entire 2024 season. Viewing this through a long-term lens, the Vikings will park McCarthy for his rookie year. This, of course, changes the Michigan product’s developmental path.

A full repair loomed as a possibility, and this situation has escalated after Monday reports indicated the rookie was dealing with knee soreness. Instead of McCarthy seeing important practice reps and taking over for Darnold at some point this season, this will keep the younger passer off the practice field. After never taking a quarterback in the top 10 prior to trading up for McCarthy, the Vikings will continue a streak of never having a first-year QB start in Week 1 (h/t Ed Werder).

Coming into the offseason, Minnesota had not given up on re-signing Kirk Cousins. But the sides did not see eye-to-eye regarding a vision or compensation, leading the six-year Vikings starter to Atlanta. That development turned this Vikes offseason into a scouting mission, with the team acquiring a second first-round pick as ammo for a trade-up. The Vikings did not end up using that Texans-obtained selection to climb up for a passer, but they made McCarthy the centerpiece of their first post-Cousins offseason. Darnold’s stopgap season suddenly becomes much more important — both for the Vikings and the former No. 3 overall pick.

Still just 27 despite going into his seventh season, Darnold has received extensive run as a starter. Despite backing up Brock Purdy throughout last season, Darnold’s start count sits at 56. While the former Jets draftee is 21-35 as a starter, he was tied to two franchises that did not have much support around him. The Jets bailed on Darnold to draft Zach Wilson in 2021, and then-Panthers HC Matt Rhule turned to Baker Mayfield via trade in 2022. Darnold received a late-season batch of starts with Carolina following Rhule’s ouster, but no starting role opened for the USC product in free agency last year.

The Vikings did offer one, signing Darnold on a one-year deal worth $10MM and outflanking the Broncos and Commanders — though, it is unclear how serious the other teams’ pursuits went — to add him. Being saddled with shaky situations, Darnold has struggled. He has never ranked higher than 25th in QBR for a season in which he took enough snaps to qualify. This could well be Darnold’s last shot, but the outlook has changed; the imminent threat to his starting job no longer exists.

Kevin O’Connell communicated with the veteran — before the team chose McCarthy — he would be the team’s season-opening starter. As teams rarely give first-rounders full seasons to sit and learn anymore, McCarthy was widely expected to see action this season. It now turns into a mid-career Darnold audition, and the presences of Justin Jefferson, Jordan Addison, Aaron Jones and T.J. Hockenson — when the tight end recovers fully, that is — present by far the best set of weaponry the QB has enjoyed (excepting 49ers practices) in his NFL career.

Still, this doubles as a tough blow for a Vikings franchise that has been unable to see a quarterback development project enjoy sustained success. Knee injuries have intervened early in Vikings first-rounders’ careers as well. A severe knee injury sustained during a 2016 preseason practice shelved 2014 first-rounder Teddy Bridgewater for nearly two seasons. Daunte Culpepper‘s starter run abruptly ended in 2005, when a knee injury provided a clear line of demarcation in the passer’s career.

Veterans — from Cousins to Case Keenum to Brett Favre — have delivered Minnesota its most success since Culpepper went down. The team is now relying on a player who has offered glimpses but one that also has not come close to delivering on his draft status. And McCarthy will need to wait until the 2025 offseason to resume full-scale preparations for his first regular-season snaps.
