Jaxson Dart was never supposed to become a quarterback who played scared. That was part of what drew John Harbaugh to him in the first place. But after a rookie season built on 487 rushing yards, nine rushing touchdowns, and more than a few punishing collisions, the Giants wanted their young quarterback to learn something just as important: when to pick his battles.

So this offseason became something of a reset. Harbaugh and his staff put Dart through quarterback school, asking him to move beyond the RPO-heavy offense he had thrived in and become more comfortable under center, in play-action and, perhaps most importantly, with making smarter decisions about when to run and when to live for the next play. One week into the season, he looked like he had made the adjustment. Then came Los Angeles and with it, the news that Dart’s promising 2026 campaign is over.

“Giants QB Jaxson Dart is expected to have knee surgery that will lead to a full recovery but end his 2026 season, sources told me and Mike Garafolo,” NFL insider Ian Rapoport reported on X. “Dart has been soliciting opinions on the injury. And the ACL is intact. But surgery is coming.”
Shortly after Rapoport’s tweet went live, fellow NFL insider Adam Schefter shed more light on the severity of Dart’s injury, adding to the concern.

“Jaxson Dart suffered damage to his MCL, PCL, and meniscus,” Schefter wrote, reposting Rapoport’s tweet. “The meniscus is the main issue.”

Now, even after he limped off the field, Dart wanted to get back into the game. The quarterback had been sent to the locker room after being evaluated, but he returned to the sideline in street clothes after halftime. Giants running back Cam Skattebo later explained that Dart “obviously probably wasn’t okay with” being kept out, but the medical staff made the call.

That detail matters because the initial picture was far more encouraging. Dart had been hurt on only the seventh snap, when Rams linebacker Byron Young hit him from the right and Josaiah Stewart’s contact sent him down awkwardly. He grabbed at his left knee, went to the blue medical tent and then walked to the locker room. At the time, the working diagnosis was a sprained MCL, not a season-ending injury.

The optimism even extended into the locker room. Giants general manager Joe Schoen told ESPN at halftime that Dart would be “OK,” while Harbaugh said the team would get an MRI and expressed relief that they appeared to have avoided the “devastating outcome” they feared. That made Tuesday’s testing the turning point.

Further evaluation revealed that the problem went beyond the MCL, with damage also found in the PCL and meniscus. The meniscus emerged as the primary concern, while Dart’s ACL remained intact.

Dart and the Giants then sought additional medical opinions before settling on surgery. The procedure will address the torn MCL and meniscus, with the recovery timeline expected to be around six months. The PCL damage is not expected to require surgery, according to Rapoport’s reporting.

As for the diagnosis, shortly after breaking the news, Ian Rapoport appeared on NFL Total Access and shared more details.

“As far as the specifics, our understanding is it is a torn meniscus and a torn MCL. Both of those will be addressed surgically,” Rapoport said. “Colleague Adam Schefter also adds that it is damages to his PCL. That, from my understanding, is not something that will be addressed surgically. Essentially, what this does is give Jaxson Dart about a six month recovery. If it was a torn ACL – which it is not, this would be about a 9 to 11 or 12 month recovery.

“This news would be much better. This news gives him a recovery that’s a little bit shorter. But obviously, those are issues that we’ll be addressing this coming offseason, not this season. The issue this season is that Jaxson Dart has now played his last down for the Giants in 2026. Jameis Winston is now QB1 for the Giants.”

That last distinction is important. Dart’s injury is season-ending, but the latest reporting does not point to the kind of prolonged recovery associated with an ACL tear. The Giants expect their 23-year-old quarterback to make a full recovery and be ready for the 2027 season.

Once Dart exited the game in Week 2, backup quarterback Jameis Winston took over, but only managed 11-of-27 completions for 111 yards and a pick in a 28-6 blowout. Rapoport agrees that Winston struggled last week, but now, with all the hopes on his throwing arm, we could see an uptick in plays.

“Full week of practice, knowing he’s going to be the quarterback, knowing the team doesn’t have just the emotional letdown of seeing their leader go down with a significant injury, the performance should be better,” Rapoport said. “But the reality is… there’s no choice for the New York Giants because Jaxson Dart is not coming back this season.”

Winston’s promotion also comes only weeks after New York made a significant commitment to keeping him around. On September 6, the Giants gave the veteran quarterback a two-year, $13 million extension through 2028, despite entering the season with no intention of making him the starter. He was retained as Dart’s safety net. Now, that safety net has become the plan.

There is at least some history to lean on. Winston already filled in for Dart twice as a rookie in 2025 when Dart missed time with a concussion, although New York lost both games. He also struggled Monday night after taking over against Los Angeles, completing only 11 of 27 passes for 111 yards and an interception.

The Giants do have third-year quarterback Jake Haener on the practice squad, giving them an in-house option behind Winston. Haener has seen limited NFL action and has primarily been a depth piece, so New York could still look outside the building for another quarterback.

But that’s not the offensive playmaker John Harbaugh spent all offseason grooming. So adding another quarterback to the depth chart is likely in the cards. However, Rapoport doesn’t believe they could get a plug-and-play solution.

“I wouldn’t be surprised if they added another quarterback. I just don’t know that it’s going to be a splashy or exciting name,” Rapoport added. “There’s been a lot of things kind of tosses around on Twitter and social media about the different quarterbacks Giants could add. I know what the Giants are doing right now is looking at all options. But the problem with the quarterback world is understanding the plays and the system is as important as basically anything else.

“In other works, you can have a really talented quarterback like, oh I don’t know, let’s just say JJ McCarthy. And if you drop him into a system he’s unfamiliar with, it’s going to be a struggle almost no matter what. We’ve seen quarterbacks who don’t play a lot in the preseason who come out and aren’t themselves till about a month into the season. Imagine having just no preseason or offseason at all. It is incredibly challenging. So whoever they bring in, I would not expect it to be someone to contribute right away. I would expect more of a depth signing.”

That leaves Winston with a particularly difficult job: he is not simply replacing a starter; he is stepping into an offense that had been designed around Dart’s mobility and development. Dart had opened 2026 by completing 23 of 29 passes for 230 yards and three touchdowns against Dallas, while adding 54 yards on 11 carries. His 134.2 passer rating helped make that performance one of the strongest opening weeks of his young career.

Even as they look at quarterback options, the Giants also need to figure out how much the other injuries from Los Angeles will affect them. Malik Nabers briefly left the game with a right shoulder injury but returned in the first half, while Brian Burns suffered a low ankle sprain and Andrew Thomas left with a groin injury.

Nabers’ situation, in particular, adds another wrinkle. He said after the game that his shoulder had “popped out” and that he “just popped it back in,” then returned to the field. He still needs further evaluation, however, and his status matters even more now that Winston is taking over for Dart.

For Harbaugh, the problem is no longer about how quickly Dart can make the next step. That development is now paused until 2027. The immediate task is figuring out how much of the offense can survive without the quarterback the Giants spent the offseason reshaping, and whether Winston can keep the season from moving further away from the plan that looked so promising one week ago.
