Jamal Adams will not play for the Vikings this season.
NFL Network’s Ian Rapoport reported Sunday that Adams’ right knee injury is season-ending. Minnesota has not yet publicly identified the exact injury, but the report confirms the fear that followed Saturday’s preseason opener against the Giants.
For Adams, the timing is particularly harsh. He joined the Vikings just before training camp, hoping to establish a new chapter after years in which injuries repeatedly interrupted his career. Instead, that chance lasted 11 defensive snaps.
The former All-Pro was hurt in the second quarter while covering a route. He went down without contact, stayed on the turf and was eventually taken from the field on a cart. O’Connell’s first post-game update offered little optimism.
“The initial exam does not look good,” O’Connell said Saturday, adding that the team would wait for imaging before confirming a diagnosis.
The emotional reaction from the Vikings’ sideline told much of the story before anyone knew the severity. Teammates and coaches visited Adams in the medical tent. Players were visibly shaken as he was carted away.
Safety Joshua Metellus explained why.
“This game takes a lot from you, and it doesn’t really give too much,” Metellus said after the game. “Constant, relentless effort to be out there to play the game he loves, and then to fall short year in and year out, I think it’s definitely been tough these past couple years.”
He had found a quick connection
Adams did not arrive in Minnesota expecting a ceremonial veteran role. He came looking to prove that he could still help a defense, and Metellus said that was apparent from the start.
“When he first came in, he wasn’t trying to be friends and buddy-buddy,” Metellus said. “He wanted to come in, prove a point, where he was at physically, where he was at in his career, to show he could still play.”
Adams had begun at linebacker after signing with the Vikings, then switched his jersey number from 54 to 32 and worked with the safeties. Defensive coordinator Brian Flores used him as a hybrid defender. He took snaps near the line of scrimmage, in the box, at safety and in coverage.
Furthermore, he was also establishing himself in the locker room. Metellus said Adams quickly embraced the team culture, and the connection was not superficial. Players had visited each other’s homes during the past few weeks. By the time the preseason opener arrived, Adams had become part of the group.
Byron Murphy Jr. described him as an immediate leader.
“He came in right away, one of our leaders, one of those guys that brought great energy,” Murphy commented. “He was just a brother to us.”
That impact matters because Adams’ career has never lacked toughness or intensity. The sixth overall pick in the 2017 draft became a three-time Pro Bowler and first-team All-Pro early in his career. His ability to blitz and play downhill made him one of football’s most distinctive defensive backs.
The problem has been availability. Adams had already missed extensive time with injuries before arriving in Minnesota, including a torn quad in 2022. He played a full 17-game season for the Raiders in 2025 after converting to linebacker, which made the Vikings’ one-year gamble understandable.
Flores saw a player whose background at safety and linebacker could unlock different packages. The team saw someone determined to make the most of another NFL chance.
Now, the Vikings must move forward without seeing how that experiment would have unfolded.
A new challenge for the secondary
Minnesota is not without options. Metellus is the most versatile defensive back on the roster, while Theo Jackson began Saturday alongside him as a starter. Jay Ward is back after missing time in concussion protocol and could play a larger role this season. Third-round rookie Jakobe Thomas should return soon from his back problems.
The club also has Tavierre Thomas, one of its most dependable special-teams players, and undrafted rookie Jacob Thomas, who intercepted a pass against the Giants and has taken advantage of additional camp reps.
Still, Adams added something no other player in the room quite matched. He carried the physicality of a linebacker, the experience of a longtime safety and the résumé of a former elite player. He also brought urgency to every practice, which is why his injury stung beyond the depth chart.
O’Connell said Adams had been building trust daily and had become a player the Vikings were counting on.
“He wasn’t taking that for granted and expecting anything,” O’Connell said. “He was earning everything, and by the day he was getting more and more and more.”
That process is now paused by another devastating injury. The Vikings may need to seek outside help. They may ask more of their young safeties. Flores may adjust his packages to fit the players who remain available.
Those are the football consequences.
The more human reality is simpler. Adams came to Minnesota after a career full of setbacks, won over a new locker room quickly and was trying to prove he still belonged. Before the regular season arrived, that chance was taken from him again. The harsh reality is that, at 30 years old, he might not have many chances left.
