Tight end Eric Saubert made the decisive two-point play for Seattle.
Seattle engineered a remarkable fightback to overcome the Los Angeles Rams in extra time, securing their spot in the postseason.
Overcoming a sixteen-point hole in the final period, the Seahawks triumphed by a single point at home, registering their fifth straight win.
While the Rams had already secured a post-season spot earlier on Sunday, the Seahawks secured their place to the play-offs after a two-year absence.
With this result, the Seahawks now lead their division's race with a 12-3 mark, replacing the Los Angeles, who dropped to the number five seed with an eleven and four standing.
Signal-caller Darnold had two interceptions but recovered to make two touchdown passes, including the second score to star receiver Jaxon Smith-Njigba in overtime.
The Rams held a 13-7 lead at the break before Kenneth Walker III burst through for a 55-yard scoring dash for the home side.
Rams defensive back Josh Wallace then took back Darnold's initial interception for a big return, leading to a one-yard touchdown by Corum on the ensuing snap.
In the fourth quarter, a scoring pass from Stafford to Nacua pushed the Rams' lead to sixteen points, but Shaheed ignited the comeback with a 58-yard return for a score.
Darnold then found AJ Barner in the endzone, and a converted conversion forced the contest into an extra period.
Although Nacua raced in for his another TD in OT, Jaxon Smith-Njigba responded in kind to set up the decisive score.
