Tight end Saubert executed the game-winning two-point conversion for the Seahawks.
Seattle engineered a stunning fightback to defeat the Los Angeles Rams in extra time, securing their spot in the postseason.
Rallying from a 30-14 deficit in the fourth quarter, the Seahawks triumphed by a single point at home, registering their fifth consecutive win.
While the Los Angeles had already secured a post-season spot earlier on game day, the Seahawks booked their return to the postseason after a 24-month hiatus.
With this outcome, the Seahawks have taken over their Conference standings with a twelve and three record, replacing the Rams, who fell to the number five seed with an eleven and four record.
Signal-caller Darnold had two picks but regrouped to make two touchdown passes, culminating in the tying TD to star receiver Smith-Njigba in the extra period.
The visitors held a 13-7 advantage at half-time before Kenneth Walker III broke free for a long scoring dash for the home side.
Rams cornerback Wallace then returned Darnold's initial pick for a big return, setting up a one-yard touchdown by Blake Corum on the next play.
In the fourth quarter, a scoring pass from Stafford to Nacua pushed the Rams' lead to 30-14, but Rashid Shaheed provided Seattle's hope with a 58-yard return for a score.
Darnold then connected with AJ Barner in the endzone, and a converted conversion forced the game into overtime.
Although Nacua scored for his another TD in overtime, Jaxon Smith-Njigba responded in kind to setup the game-winning conversion.
