Vikings QB J.J. McCarthy Undergoes Second Knee Procedure

J.J. McCarthy underwent meniscus surgery in August, and with a full repair being required he will be sidelined for his entire rookie season. The Vikings first-rounder’s rehab process recently led to a second procedure being deemed necessary.

A biologic injection took place earlier this week, ESPN’s Kevin Seifert reports. The procedure was aimed at reducing swelling in the knee which developed as McCarthy ramped up his rehab. Ben Goessling of the Minneapolis Star Tribune confirms the injection (rather than another surgery altogether) is the extent of what took place. Most significantly, this development is not expected to alter the No. 10 pick’s recovery timeline. Being available for the start of the 2025 campaign remains the expectation in this case.

“As his rehab has picked up, we noticed a little swelling in there and just with the time that we do have… we just wanted to make sure there was no cause for concern,” head coach Kevin O’Connell confirmed (via Seifert). “All reports were very positive and he’s on the original timetable and in good shape.”

McCarthy was one of six quarterbacks selected within the first 12 picks of the 2024 draft, although his NFL ceiling has been a talking point given his limited usage in the passing game in college. The 21-year-old helped guide Michigan to an undefeated season and a national title in 2023, but the team’s reliance on its defense and rushing attack left McCarthy with greater uncertainty than many of his fellow QB prospects regarding his abilities as a passer. Minnesota nevertheless committed to him as the franchise’s Kirk Cousins successor.

Veteran stopgap Sam Darnold was atop the depth chart at the start of training camp, and McCarthy’s injury left him as the undisputed starter for the campaign. Darnold enjoyed a very strong start to the year, one which will determine his market value during the spring. He has, however, seen a downturn in effectiveness recently, including a three-interception outing against the Jaguars last week. Still, the former No. 3 pick is set to remain Minnesota’s QB1 through the rest of the year.

Beyond that point, McCarthy will obviously be the favorite to take on starting duties, especially if Darnold departs. Having missed an entire year of development, though, the former’s readiness will no doubt be a major talking point in 2025. Nevertheless, McCarthy remains on track to be fully healthy in time for the start of next year.
