New York Giants quarterback Jaxson Dart's knee injury is far worse than the team initially feared, and the 23-year-old signal-caller is now facing the possibility of season-ending surgery, multiple reports confirmed Tuesday. What was believed Monday night to be a sprained MCL — an injury that typically costs a player four to six weeks — proved significantly more serious after further testing. Dart went down just seven plays into the Giants' Week 2 “Monday Night Football” game against the Los Angeles Rams, crushed by two defenders on the opening drive of an eventual 28-6 loss at SoFi Stadium. The news delivers a gut punch to a franchise riding high after a season-opening victory, and it thrusts veteran backup Jameis Winston into the starting role for the foreseeable future.
The Hit That Changed the Giants' Season
Dart limped off the field in the first quarter following a crushing hit from both sides by Rams defenders Byron Young and Josaiah Stewart. He immediately clutched his left knee and was in obvious pain before walking to the locker room. After undergoing initial tests, Dart emerged on the sideline in team-issued warmups, a moment that briefly calmed the New York sideline.
General manager Joe Schoen told ESPN on Monday night that Dart was “going to be OK,” and head coach John Harbaugh said in his postgame news conference that the initial prognosis suggested the Giants and Dart had avoided a “devastating outcome.”
That optimism faded dramatically by Tuesday. A Tuesday MRI revealed the damage to Dart's left knee was worse than initially believed, and the Giants now fear their franchise quarterback is looking at potentially season-ending surgery, a source confirmed to The New York Post. Even in a best-case scenario, Dart is expected to miss significant time.
From MCL Sprain to Surgery Talk: How It Unfolded
The sequence of events shows how quickly the Giants' outlook shifted from relief to concern:
Monday, Sept. 21 — The Injury. On the opening drive of the Giants' Week 2 matchup in Inglewood, California, Dart absorbed simultaneous contact from Young and Stewart and crumpled to the turf clutching his knee. He was ruled out for the rest of the game, and Winston finished the contest as the Giants managed just one field goal in a 28-6 defeat.
Monday night — Cautious optimism. Schoen's “going to be OK” comment and Harbaugh's reference to avoiding a “devastating outcome” suggested the franchise believed Dart had escaped with a relatively minor MCL sprain.
Tuesday, Sept. 22 — The grim turn. After the team returned from the West Coast, an MRI revealed more extensive damage than the initial diagnosis indicated. NFL insider Tom Pelissero of Netflix reported that Dart is now seeking additional medical opinions to determine whether surgery is required.
What Dart's Injury Means for the Giants Offense
The Giants built their 2026 plans around Dart, who delivered a stellar performance in the team's season-opening win. Losing him for any stretch forces Winston into the spotlight — a veteran with arm talent and a well-documented turnover problem.
Winston, the No. 1 overall pick of the Tampa Bay Buccaneers in 2015, signed a two-year, $13 million contract extension earlier this month. In three games for the Giants last season, he threw for 567 yards with two touchdowns and two interceptions. Across his 12-year NFL career with the Buccaneers, Saints, Browns and Giants, Winston has thrown 114 interceptions, a number that hangs over an offense that will need to play mistake-free football without its starter.
Against the Rams, Winston managed just 111 passing yards as the offense stalled possession after possession. Wide receiver Malik Nabers also left the game with an injury, further thinning a group the Giants will lean on to steady the ship.
Harbaugh, in his first season at the helm, struck a defiant tone Tuesday while acknowledging the challenge ahead. “I can tell you, if you get punched in the gut, are you going down?” Harbaugh said. “Are you going to crumple to the ground... and just rot away and wither away into the dust? I don't think so. How many people face gut punches every single day?”
Where Things Stand: Latest on Dart's Knee
As of Tuesday evening, the Giants had not announced a final decision on Dart's status. Harbaugh declined to offer specifics in a video call with reporters, framing the situation as an ongoing medical evaluation.
“I'm not commenting on all the different reports. It's not my place to do that,” Harbaugh said. “It's an ongoing conversation about the health of a player. In due time, everybody is going to know what the outcome is.”
He added: “I don't even know all the answers, because I'm not the person who is hurt, and I'm not the doctor, either.”
What's Next for Dart and the Giants
Dart's additional medical consultations in the coming days will determine whether he undergoes season-ending surgery or attempts a recovery path that could still cost him a large chunk of the year. Either way, Winston is expected to start when the winless Tennessee Titans visit MetLife Stadium on Sunday.
The schedule offers the Giants a chance to stabilize. After the Titans, they face the Arizona Cardinals before visiting the Washington Commanders, who lost starting quarterback Jayden Daniels to a dislocated left elbow. That Oct. 11 matchup could carry surprising stakes for two teams now leaning on their backups.
For Dart, a former Ole Miss star who seized the starting job in New York, the road ahead hinges on a second opinion. For the Giants, the road ahead hinges on Winston — and on a locker room determined to prove it can absorb the blow.
The Bottom Line: Key Points on Dart's Injury
