Receiver Saubert made the decisive two-point conversion for Seattle.
The Seattle Seahawks engineered a stunning fightback to overcome the Rams in extra time, clinching their spot in the postseason.
Rallying from a 30-14 hole in the final period, the Seahawks triumphed by a single point at home, notching their fifth consecutive victory.
While the Rams had become the first to earn a post-season berth earlier on Sunday, the Seahawks secured their place to the postseason after a two-year hiatus.
With this result, the Seahawks now lead their division's standings with a twelve and three record, supplanting the Los Angeles, who fell to the fifth playoff position with an eleven and four standing.
Signal-caller Darnold threw two picks but regrouped to make two touchdown passes, including the tying score to wideout Jaxon Smith-Njigba in overtime.
The visitors held a six-point advantage at half-time before Walker burst through for a 55-yard touchdown run for Seattle.
Los Angeles defensive back Wallace then returned Darnold's initial interception for a big return, leading to a one-yard touchdown by Blake Corum on the next play.
In the final stanza, a touchdown from Stafford to Puka Nacua pushed the Rams' lead to sixteen points, but Shaheed ignited the comeback with a 58-yard return for a score.
Darnold then found Barner in the endzone, and a converted conversion sent the contest into an extra period.
Although Puka Nacua raced in for his second TD in OT, Smith-Njigba answered in kind to setup the game-winning score.
