Jaxson Dart Undergoes Knee Surgery; Jameis Winston Starts
Updated: Sep 28
September 28 update: Giants trade for J.J. McCarthy
The Giants have acquired J.J. McCarthy from Minnesota for a 2027 fifth-round pick, pending McCarthy passing a physical. The trade adds a developmental quarterback after Dart’s season-ending surgery, but it does not change the immediate starter: John Harbaugh said Jameis Winston will start again against Arizona.

September 25 update: Dart undergoes season-ending knee surgery
Jaxson Dart underwent left-knee surgery Friday, September 25, after the Giants placed him on injured reserve Thursday. ESPN reported, through NFL.com’s league roundup, that the procedure was believed to address his meniscus and MCL. The previously reported injury also involved the PCL, while the ACL remained intact. New York still has not announced Dart’s individualized recovery timetable, and John Harbaugh’s earlier reference to a possible postseason return remains conditional.
Jameis Winston remains the confirmed Week 3 starter against Tennessee, with Jake Haener expected to serve as the backup. The next meaningful checkpoint is the Giants’ post-operative guidance—not an estimate inferred from a generic recovery range.
The Friday procedure update is documented in NFL.com’s September 25 league roundup.

September 24 update: Harbaugh confirms surgery and Winston as starter
Giants coach John Harbaugh confirmed that Jaxson Dart required season-ending left-knee surgery after damage to the MCL, PCL and meniscus, with the ACL intact. Dart underwent the procedure Friday, September 25. Harbaugh had left open a postseason return, but that possibility remains conditional. The club has not announced an individualized recovery timetable.
Harbaugh also confirmed Jameis Winston will start Sunday against Tennessee. Jake Haener is expected to serve as the Week 3 backup, and the Giants are evaluating additions at quarterback, including trade possibilities. NFL Network reported Jimmy Garoppolo as a potential candidate; no signing or trade has been announced.
NFL.com’s September 24 confirmation supplies the coach’s statements and the current quarterback plan.
September 23 update: Dart to undergo season-ending knee surgery
NFL Network and ESPN reported Wednesday that Jaxson Dart required season-ending left-knee surgery after consulting multiple medical opinions. The reported damage involved the MCL, PCL and meniscus; his ACL remained intact. Dart underwent the procedure Friday, September 25, after the Giants placed him on injured reserve.
The latest reporting is more serious than the initial postgame belief that Dart had sustained an isolated MCL sprain. NFL.com reported Wednesday that the injury includes MCL, PCL and meniscus damage while the ACL remains intact, and that Dart will undergo season-ending surgery. New York’s formal announcement remains pending, but the treatment decision is now reported as made rather than merely possible.
John Harbaugh has named Jameis Winston the Giants’ starter beginning in Week 3, while Dart moves toward surgery. Harbaugh left open a postseason return for Dart, so “season-ending” currently refers to the regular-season plan rather than an absolute playoff exclusion. The next factual checkpoint is New York’s announcement of the procedure date and recovery outlook. No outside quarterback acquisition has been announced.
NFL Network and ESPN reported that Jaxson Dart suffered damage to the MCL, PCL and meniscus in his left knee while the ACL remained intact. Dart underwent season-ending surgery Friday, September 25, after consulting multiple medical opinions. The Giants have not announced an individualized recovery timetable.
The Giants’ official injury update identified the injury as a left-knee issue and confirmed that Dart would not return. NFL.com also reported the early exit, while Reuters reported that X-rays were negative, that the injury is believed to be an MCL sprain and that an MRI is scheduled Tuesday. Those details narrow the concern but do not establish a final diagnosis or recovery timetable.
What happened to Jaxson Dart
The play came with 11:20 remaining in the first quarter. Dart released a third-down pass while Rams defenders Byron Young and Josaiah Stewart arrived from opposite angles. His left knee appeared to buckle as he absorbed the contact. Dart immediately grabbed the knee, then eventually stood and walked off the field. He was examined in the sideline medical tent before walking to the locker room under his own power.
The Giants’ official in-game status below documented the knee injury before the team ruled Dart out at halftime.
Dart completed 3 of 5 passes for 20 yards on New York’s opening drive. Jameis Winston entered on the next Giants possession and handled the offense for the rest of the night. Football Nation’s Giants-Rams Week 2 preview has also been updated to reflect the quarterback change, while the leaguewide Week 2 injury tracker now points readers to this canonical report.

What is confirmed — and what is not
The current picture is materially clearer than it was on game night: Dart injured his left knee, further testing revealed multi-structure damage, the Giants placed him on injured reserve, and he underwent surgery Friday. NFL Network and ESPN reported MCL, PCL and meniscus damage with an intact ACL. The Giants’ post-operative rehabilitation guidance is the next authoritative checkpoint.
Giants general manager Joe Schoen told ESPN sideline reporter Laura Rutledge that Dart was “going to be OK,” according to the New York Post’s account. That comment reflected the initial postgame outlook, but subsequent testing produced a far more serious reported picture. NFL Network and ESPN now say Dart will undergo season-ending surgery, so Schoen’s earlier reassurance should not be treated as a current medical prognosis.
Why the injury matters to the Giants
Dart is not simply the player listed first on a depth chart. He is the second-year quarterback around whom New York is trying to build its next competitive core. As a rookie in 2025, he threw for 2,272 yards with 15 touchdowns and five interceptions in 14 games, including 12 starts. He also added 487 rushing yards and nine rushing touchdowns, production that made his mobility a central part of the offense.
The 2026 opener reinforced that upward trajectory. In the Giants’ 28-20 win over Dallas, Dart completed 23 of 29 passes for 230 yards and three touchdowns without an interception. That performance was evidence of a more controlled passing game, not just another explosive rushing day. Losing him for any meaningful stretch would change the offense’s identity and slow an important evaluation season.
Winston can keep the passing game functional, and his willingness to attack downfield gives New York a credible emergency plan. But he does not offer Dart’s combination of designed-run value, improvisation and chemistry with the younger skill players. The staff would likely reduce quarterback movement, lean harder on protection and ask Winston to win from the pocket if Dart cannot play.
Fantasy football impact
The fantasy consequence is now much clearer. Dart belongs in an injured-reserve slot where one is available and can be dropped in most shallow one-quarterback redraft leagues after the Giants formalize the plan. Winston becomes an immediate superflex priority and a matchup-based option in one-quarterback formats. The broader Week 3 fantasy fallout report will track the practice-week consequences.
For Giants pass catchers, Winston would create a different distribution profile rather than an automatic downgrade. He has historically pushed the ball aggressively, which can preserve ceiling outcomes for outside receivers, but the offense could become less efficient and face more negative plays. Managers should avoid reacting to one partial game before New York clarifies the starter and the injury severity.
Dart’s recovery milestones are the next checkpoints
Harbaugh’s confirmation and the specialist consultations produced the decisive update: the injury reportedly includes the MCL, PCL and meniscus, and Dart underwent surgery Friday, September 25. The next useful information is the Giants’ post-operative recovery plan. An intact ACL is meaningful, but it does not justify assigning a 2027 return date before the club and surgeons provide one.
Football Nation’s Puka Nacua status report and the Giants-Cowboys prediction review provide additional context for the injuries and early-season form surrounding this matchup and New York’s schedule.
Football Nation verdict
The intact ACL is important, but damage to the MCL, PCL and meniscus makes this a complex knee injury rather than the isolated sprain first discussed after the game. Football Nation’s position is straightforward: plan for Winston to lead the Giants for the rest of the regular season, preserve Dart only in dynasty or injured-reserve formats, and wait for New York’s post-operative rehabilitation details before assigning a 2027 return timetable.
