Jaxson Dart lasted seven plays on Monday Night Football. The New York Giants lasted about as long.
Dart went down on the opening drive at SoFi Stadium. The Giants ruled him out early in the third quarter. He watched a 28-6 loss to the Rams from the sideline in a knee brace.
The latest Jaxson Dart injury update points to a sprained MCL. X-rays came back negative. Dart underwent an MRI on Tuesday, and the grade of that sprain now drives everything.
Prediction markets moved before any of it got confirmed. Giants playoff contracts on Polymarket sit at 26 cents, down from the high 40s at kickoff. The NFC East trades at 10 cents. New traders can open those markets with the Polymarket promo code ACTION, which turns a $10 deposit into $50 in trading credits.
What Happened to Jaxson Dart?
Third-and-8 on the opening series. Dart held the ball to throw deep. Rams linebacker Byron Young hit him from the right side and drove him into Josaiah Stewart, who undercut his legs. Dart's left knee absorbed the full weight.
He grabbed at the knee, went to the blue medical tent, then walked to the locker room with a limp. He finished 3-of-5 for 20 yards.
Dart lobbied to return. The Giants refused and took his uniform to end the argument. General manager Joe Schoen told the ESPN broadcast that Dart was going to be OK. Head coach John Harbaugh, asked about the MCL report, said it was "in the neighborhood of it."
Jameis Winston finished 11-of-27 for 111 yards and an interception.
How Long is Jaxson Dart Out?
Any timeline stays an estimate until the MRI goes public. Here's the framework the market uses:
- Grade 1 (mild): 1 to 2 weeks
- Grade 2 (partial): 4 to 6 weeks
- Grade 3 (complete): 6 weeks or more, surgery possible
Broadcast cameras caught a sideline exchange between Harbaugh and a staffer that viewers read as "he's gonna be out four to six weeks." That fits a Grade 2. Treat it as unconfirmed until the team says it out loud.
One thing matters more than the number. Isolated MCL sprains heal without surgery and don't end seasons. Monday night's pricing suggested otherwise.
Giants Odds on Polymarket After the Dart Injury
Live Polymarket prices:
- Giants to make the playoffs: 26¢ (26%)
- Giants to win the NFC East: 10¢ (10%)
- Giants to win the Super Bowl: 2¢ (2%)
Two things jump out.
The market hasn't bought the good news. Playoff contracts traded near 47 cents at kickoff and bottomed in the low 20s during the third quarter. By Tuesday, the Jaxson Dart injury update reads as an MCL sprain rather than anything structural; Schoen said on air that Dart was fine, and the price has crawled back only to 26 cents.
The division already looks gone. At 10 cents, the NFC East trades a few cents above a Super Bowl that requires four playoff wins. The market puts New York's remaining postseason value in the wild card. That's a harsh read on a 1-1 team that beat Dallas eight days ago.
Sportsbooks reacted slower and less consistently. FanDuel cut the Giants from +4500 to +8000 to win the Super Bowl within minutes of the hit. DraftKings held at +4500 into Tuesday morning. Polymarket's 2 cents prices the Giants longer than either.
One caution on the longshots. Contracts at 2 and 3 cents carry thin liquidity, so the spread costs more than the headline price suggests, and large orders move the market against you. The playoff contract at 26 cents holds far deeper liquidity and handles size better. Anyone starting from scratch should note that the Polymarket promo code ACTION covers the first $10 deposit with $50 in credits, which is enough to take a position in the deeper market rather than the thin ones.
A Brutal NFL Week for Young Quarterbacks
Three of the league's most valuable young passers went down in Week 2. Two of them change the math on the Giants' division price.
Jayden Daniels, Commanders. Daniels dislocated the same elbow that cost him time in 2025, bracing himself on the ground against Dallas. Washington ruled him out for Week 3 and handed the offense to Marcus Mariota with no timeline attached. The Giants visit Washington in Week 5. With two of four NFC East starters hurt, every division contract deserves a second look.
Caleb Williams, Bears. A cart took Williams off the field in the fourth quarter against Minnesota. The diagnosis came back as a hamstring, and he sits week-to-week. Here's the instructive part: Chicago's playoff contracts dropped roughly 14 cents on the cart alone, before anyone knew the injury wasn't structural. That same pattern sits inside the Giants' 26 cents right now.
Giants vs. Titans: The Market That Stays Open
Every Dart contract from Monday settled hours ago. Week 3 carries the live action.
New York (1-1) hosts Tennessee (0-2) at MetLife Stadium on Sunday at 1 p.m. ET. Winston takes the snaps. The Cardinals follow, then the trip to Washington.
A four to six week timeline hands Winston that entire stretch. That's three games of Giants markets priced off a quarterback who completed 41% of his passes on Monday, against a Titans team still looking for its first win.
