Tight end Eric Saubert made the decisive two-point conversion for Seattle.
The Seattle Seahawks staged a stunning fightback to overcome the Los Angeles Rams in extra time, clinching their spot in the postseason.
Overcoming a 30-14 deficit in the final period, the Seahawks emerged victorious 38-37 at home, notching their fifth straight win.
While the Rams had already secured a post-season berth earlier on game day, the Seattle team booked their return to the play-offs after a 24-month hiatus.
With this outcome, the Seattle now lead their division's standings with a twelve and three record, supplanting the Rams, who dropped to the fifth seed with an 11-4 record.
Quarterback Darnold threw two picks but recovered to deliver two touchdown passes, culminating in the second TD to wideout Jaxon Smith-Njigba in overtime.
The visitors held a six-point lead at half-time before Kenneth Walker III burst through for a 55-yard touchdown run for the home side.
Los Angeles defensive back Wallace then returned Darnold's initial interception for 56 yards, setting up a one-yard score by Corum on the ensuing snap.
In the final stanza, a touchdown from Matthew Stafford to Puka Nacua extended the advantage to 30-14, but Rashid Shaheed ignited the hope with a spectacular punt return.
Darnold then connected with AJ Barner in the end zone, and a converted two-point play forced the contest into an extra period.
Although Puka Nacua raced in for his another touchdown in OT, Smith-Njigba answered in kind to setup the game-winning score.
