Jaxson Dart's breakout start to the 2026 NFL season hit a painful wall on Monday Night Football, when the New York Giants' second-year quarterback suffered a sprained left MCL on the team's very first drive against the Los Angeles Rams. Dart was sandwiched between two Rams pass rushers, Josaiah Stewart and Byron Young, and his left knee bent awkwardly as he absorbed the hit in the pocket. He limped off under his own power and, according to ESPN's Jordan Raanan, even tried to talk his way back into the game — but the Giants held him out, and veteran Jameis Winston finished a 28–6 blowout loss at SoFi Stadium. The Giants are now awaiting MRI results to confirm the severity and a timeline that could sideline their young signal-caller for several weeks.
How Jaxson Dart Went Down: Inside the First-Drive Hit
The injury came on the Giants' opening offensive series, before the offense could build on a season-opening victory that had suddenly made New York one of the NFL's early storylines. Dart was hit high and low after Rams defenders Josaiah Stewart and Byron Young beat the Giants' tackles off the edge. Video replay showed his left leg shift in an awkward direction while he was airborne, and he immediately grabbed for his knee.
Dart was able to walk to the sideline gingerly but was in clear and visible pain. In a detail that suggests the injury may not be as severe as it initially looked, Raanan reported during the broadcast that Dart tried to convince the coaching staff to let him back in — they declined. He was ruled out, and Winston, the team's veteran backup, took over under center.
Without Dart, the offense that overpowered Dallas in Week 1 with a ground-and-pound approach could not find its footing. Matthew Stafford "looked more like the reigning MVP," as OutKick's Scott Thompson wrote, and the Rams — playing with a returning Aaron Donald but without Myles Garrett — cruised to a 28–6 win. The defeat dropped the Giants to 1–1 and, far more importantly, left the health of their franchise quarterback in question.
From Breakout Week 1 to a Monday Night Blowout: The Timeline
Dart entered Monday night on a high. Just eight days earlier, on Sept. 13, he made his first career opening-game start and completed 23 of 29 passes for 230 yards and three touchdowns in a 28–20 win over the Dallas Cowboys — the Giants' first Week 1 victory since 2022 and the first statement of the John Harbaugh era.
The sequence that followed was a sharp reversal:
- Sept. 13 (Week 1): Dart shines against Dallas, throwing three touchdowns without an interception in a 28–20 win.
- Sept. 21, first quarter (Week 2): Dart is sandwiched by Stewart and Young on the opening drive and leaves with a left knee injury.
- Sept. 21, postgame: Harbaugh says Dart is "in the neighborhood" of a sprained MCL, adding it is "not that outcome, the devastating outcome." NFL insider Ian Rapoport reports a sprained MCL that avoids a torn ACL, with X-rays negative.
- Sept. 21, during broadcast: A trainer is seen on the broadcast seemingly telling Harbaugh that Dart could be out "four to six weeks."
- Sept. 22 (Tuesday): The Giants return to New Jersey, where Dart is scheduled to undergo an MRI to confirm the diagnosis and timeline.
Why This Injury Hits Different: Dart's High-Contact Style and a Bigger Problem
For anyone who has followed Dart's brief NFL career, the concern goes beyond a single play. The Ole Miss product has built a reputation as a dual-threat quarterback who plays with a "linebacker at quarterback" physicality, as The Guardian described it. He ran for nine touchdowns as a rookie in 2025 — the second most among NFL quarterbacks — and recorded five games in which he both threw and ran for a score.
That style comes with risk. As a rookie, Dart underwent five concussion evaluations, including a diagnosed concussion in Week 10 of 2025 against the Chicago Bears that forced him to miss two games — and prompted Winston to start in his place. The Giants spent the offseason urging Dart to protect himself and absorb less contact. Dart, for his part, has pushed back on the idea that he needs to change.
"This is football. Like, I'm going to get hit if I'm in the pocket or outside the pocket," Dart said in late 2025. "We're not playing soccer out here. You're going to get hit. Things happen. It's just part of the game."
Monday night's injury was a reminder that the danger is not limited to designed runs — Dart was hurt in the pocket on a passing play. It also arrived in a Week 2 that has been brutal on quarterbacks around the league, and it compounds a mounting injury list for New York: edge rusher Brian Burns (low left ankle sprain), left tackle Andrew Thomas (groin) and wide receiver Malik Nabers (right shoulder) all went down against the Rams.
Where Things Stand: MRI Pending as the Giants Return Home
The Giants are describing Dart's injury cautiously until imaging provides clarity. "We'll get an MRI [Tuesday] and have a really good feel for it and give you more information then," Harbaugh said after the game. He added that the team is relieved the early read is not more serious: "The fact that it's not that outcome, the devastating outcome, is really good news."
Dart returned to the sideline in the second half in street clothes and did not speak to reporters. He is "clearly going to miss time," according to the New York Daily News, with the initial "four to six weeks" estimate from the broadcast serving as the working assumption until the MRI says otherwise.
Asked about the Giants' long list of injuries, Harbaugh grew frustrated but struck a defiant tone: "None of these injuries are life-threatening... This is football. This is the NFL. This is what you do."
What's Next: Jameis Winston Under Center and a Short Week Ahead
Barring a major surprise, Winston will start Sunday against the Tennessee Titans, a matchup the Giants will approach on a short week following the Monday night road trip. Winston filled in for Dart after his 2025 concussion and brings a different, less mobile skill set to the offense — a factor made more significant by the potential absence of left tackle Andrew Thomas.
If the MCL sprain is confirmed and the four-to-six-week estimate holds, the Giants' early-season momentum under Harbaugh will be tested immediately. The team began the year with genuine buzz after knocking off the Cowboys; keeping that momentum alive now hinges on Winston, a banged-up offensive line and a receiving corps still finding its rhythm.
The Bottom Line: What to Know About Jaxson Dart's Injury
- Dart sprained his left MCL on the Giants' first drive of Monday Night Football against the Rams and did not return.
- The injury came on a sandwich hit by Rams defenders Josaiah Stewart and Byron Young; his knee bent awkwardly as he was hit.
- Harbaugh said the early read is "in the neighborhood" of a sprained MCL — not the "devastating" outcome of a torn ACL — with X-rays negative.
- A broadcast moment suggested a possible "four to six weeks" absence; an MRI on Tuesday will confirm the exact timeline.
- Jameis Winston is expected to start Sunday against the Tennessee Titans.
