Jamal Adams, who was carted to the locker room after an extended stay in the medical tent, won't return to the game, the Vikings said.

Jamal Adams' injury prognosis doesn't sound good, based on what Kevin O’Connell said on the Vikings' broadcast coming out of halftime. "You're just crushed for him," O’Connell said. "We're gonna miss him. You absolutely hate to see that."

Going back and reviewing the plays, it looked like Jamal Adams stumbled in pass coverage as Calvin Austin III ran a crossing route. Stayed down and grabbed at his lower half. Reactions from teammates told the whole story. https://t.co/Q0qjSVnwNj

Jamal Adams Injury Tracker: Everything We Know About Vikings' Veteran After Saturday's Exit

This wasn't the start to the preseason that the three-time Pro Bowl defender wanted.

Saturday was supposed to be an exciting day, as it marked the Vikings' 2026 preseason debut. Fans were looking forward to seeing how Minnesota's offseason additions—from quarterback Kyler Murray to rookie pass rusher Caleb Banks—would perform in the first taste of exhibition action. Instead, the Vikings' faithful were left wondering if Jamal Adams would be okay.

It was a scary moment at MetLife Stadium when Adams needed to be carted off the field after suffering a non-contact injury in the second quarter. Although it's too early to give a diagnosis, the early buzz among experts and fans is that the situation isn't good, and there's a good chance that the Vikings' recent signing will miss some time.

Here's what we already know about Adams's injury, as well as any updates that the Vikings will provide in the coming days.

Analyzing Jamal Adams's injury

As mentioned above, Adams didn't even make it to halftime before disaster struck. SKOR North's Thor Nystrom shared a video of the incident shortly after it happened, and viewers can see how the former All-Pro contributor went crashing to the ground without even being touched.

More often than not, that's the sign of a severe injury.

Making matters worse is the fact that Adams couldn't get off the field with his own power and needed to be carted off for medical attention (h/t VikingzFanPage).

With Adam's outlook up in the air, a confidence-inspiring update from head coach Kevin O'Connell is exactly what fans need. Unfortunately, that wasn't what they received once the Vikings emerged from halftime. O'Connell said that the team is "gonna miss" Adams and that everyone is "just crushed for him."

You're just crushed for (Jamal), the role he was kind of paving for himself and just having a personality, experience, toughness that he brought in such a short amount of time. We're going to miss him.

Kevin O'Connell on Jamal Adams

Although an official diagnosis hasn't been released, the fact that O'Connell went out of his way to say that the Vikings would "miss" Adams can't be ignored. It sounds like early diagnosis has determined that the 30-year-old won't be back anytime soon, if his season isn't completely over already, that is.

Previous injury history

Despite all the talent and accolades he possesses, one thing that Adams hasn't been able to overcome in his career is an ever-lasting feud with the injury bug.

The 2016, 2017 and 2025 seasons are the only ones where Adams played every possible regular-season game. He's played 12 or fewer games six times in nine seasons so far, which includes a total of 15 between 2022 and 2024. And it isn't as if it's one issue that's constantly plaguing him, having dealt with injuries that affected his groin, ankle, head, labrum and quad since joining the league, per Draft Sharks.

It's still too early to say if one of those previous injuries is behind Adams's latest ailment, at least until more testing is done. Nevertheless, it's starting to look like last year's fully healthy run with the Raiders was a one-off situation as the Lewisville, TX native finds himself on the sidelines yet again.

Head Coach Kevin O'Connell has said that Jamal Adams suffered a right knee injury in today's game and that initial examinations don't look good.
