Tight end Saubert executed the decisive two-point play for the Seahawks.
Seattle staged a remarkable fightback to defeat the Los Angeles Rams in overtime, clinching their spot in the postseason.
Rallying from a 30-14 hole in the fourth quarter, the Seahawks triumphed by a single point at home, registering their fifth consecutive victory.
While the Los Angeles had already secured a playoff spot earlier on Sunday, the Seattle team booked their return to the postseason after a two-year absence.
With this result, the Seattle now lead their division's race with a 12-3 record, supplanting the Los Angeles, who fell to the fifth seed with an 11-4 record.
Quarterback Darnold threw two picks but recovered to deliver two touchdown passes, including the second score to wideout Smith-Njigba in the extra period.
The Rams held a six-point lead at half-time before Walker burst through for a 55-yard scoring dash for the home side.
Rams defensive back Wallace then returned Darnold's initial pick for 56 yards, leading to a one-yard touchdown by Blake Corum on the next play.
In the final stanza, a scoring pass from Stafford to Nacua pushed the advantage to sixteen points, but Shaheed ignited the comeback with a spectacular return for a score.
Darnold then connected with AJ Barner in the end zone, and a successful two-point play sent the game into overtime.
Although Puka Nacua scored for his second touchdown in OT, Jaxon Smith-Njigba answered in kind to set up the game-winning conversion.
