SEATTLE (Interstat) — In a game defined by relentless momentum swings and a staggering fourth-quarter collapse, the Seattle Seahawks authored a miraculous overtime escape to defeat the Los Angeles Rams 38-37 on Thursday night at a raucous Lumen Field.

A crowd of 68,853 witnessed a contest that saw the Rams dominate for three quarters, only for the Seahawks to storm back from a 23-point deficit in the final period before securing an improbable victory in the extra session.

The game’s defining sequence, and its most important part, unfolded in the final minutes of regulation and into overtime. Leading 37-30 with under seven minutes to play in the fourth quarter, the Rams appeared to have the game in hand. But a missed 48-yard field goal by Harrison Mevis with 2:07 remaining gave Seattle life at its own 29-yard line, trailing by seven.

The Seahawks’ ensuing drive stalled, but they forced a Rams punt and got the ball back at their own 15 with just 42 seconds left. Quarterback Sam Darnold, who struggled for much of the night, then engineered a frantic, 85-yard touchdown drive in just 29 seconds. The series was capped by a 26-yard touchdown pass to tight end AJ Barner with six seconds left. Darnold then connected with Zach Charbonnet on the two-point conversion, a play initially ruled incomplete but overturned by replay review, tying the game at 37 and forcing overtime.

In the extra period, the Rams struck first. Matthew Stafford, who threw for 387 yards, immediately found Puka Nacua for a 41-yard touchdown on the opening drive, putting Los Angeles back ahead 37-30 under the current overtime rules.

Needing a touchdown and a two-point conversion to win, Seattle’s offense took the field. Darnold, displaying the poise that had eluded him earlier, methodically moved the Seahawks downfield. He completed key passes to Jaxon Smith-Njigba and Cooper Kupp, setting up a first-and-goal. On third down from the 4-yard line, Darnold fired a pass to Smith-Njigba for the touchdown. Then, facing a win-or-lose play, Darnold found tight end Eric Saubert in the back of the end zone for the successful two-point conversion, sealing a 38-37 victory and triggering a bedlam on the field.

The comeback obscured what was for three quarters a commanding Rams performance. Los Angeles built a 20-7 halftime lead behind a methodical offense and a defense that harassed Darnold. That lead expanded to 30-14 late in the third quarter after Rams cornerback Josh Wallace intercepted a Darnold pass intended for Rashid Shaheed and returned it 56 yards to the Seattle 1-yard line. Blake Corum punched it in on the next play.

Stafford’s second touchdown pass, a 1-yarder to Nacua early in the fourth, pushed the Rams’ advantage to 37-14, seemingly putting the game out of reach. Nacua was spectacular throughout, finishing with nine receptions for 168 yards and that touchdown.

The Seahawks’ rally began in earnest with a trick play. Wide receiver Rashid Shaheed took an end-around 31 yards to the Rams’ 26. On the next play, Darnold hit Barner for a 26-yard score, though the two-point try failed, making it 37-22. After a quick Rams punt, Seattle needed just two plays to score again, with Kenneth Walker III breaking a 55-yard touchdown run. The subsequent two-point conversion, a pass to Charbonnet, pulled Seattle within 37-30, setting the stage for the final drama.

Walker was a catalyst for Seattle, rushing for 94 yards on just nine carries, including his long touchdown. Smith-Njigba led Seahawks receivers with six catches for 75 yards and the overtime touchdown.

Defensively, the Seahawks were led by a busy linebacker corps. Ernest Jones IV and Drake Thomas each recorded 12 tackles, while safety Nick Emmanwori had 11. The unit, while gashed for large chunks of the game, made critical stops late and produced the overtime interception by Jones that gave Seattle its chance to win.

The loss overshadowed a strong performance from Stafford and the Rams’ offense, which amassed 469 total yards. Kyren Williams rushed for 69 yards on 22 carries, and Corum added 44 yards and a touchdown on the ground.

With the victory, Seattle improves to 12-3 and solidifies its hold on the NFC West lead. The Rams fall to 11-4, their playoff positioning still strong but their path to a division title now significantly more difficult. The two teams split their season series, with the Rams having won 21-19 in Los Angeles in November.

The game’s combined score of 75 points wildly surpassed the pregame over/under line of 42.5, and the result defied the projections of Interstat’s game simulator, which had forecast a 31-23 Seattle win. The Seahawks were also slight pregame favorites, installed at -1.5.

Seattle travels to face the Carolina Panthers next, while the Rams head to Atlanta to take on the Falcons in their next contest.
