Tight end Saubert made the decisive two-point conversion for the Seahawks.
The Seattle Seahawks staged a stunning comeback to overcome the Rams in extra time, clinching their spot in the postseason.
Overcoming a 30-14 hole in the final period, the Seattle squad emerged victorious by a single point at home, notching their fifth straight win.
While the Los Angeles had become the first to earn a playoff berth earlier on game day, the Seahawks secured their place to the postseason after a two-year absence.
With this outcome, the Seattle now lead their division's race with a 12-3 mark, supplanting the Los Angeles, who fell to the fifth playoff position with an eleven and four standing.
Quarterback Sam Darnold had two interceptions but recovered to make two touchdown passes, culminating in the second TD to star receiver Smith-Njigba in the extra period.
The visitors held a six-point lead at half-time before Walker broke free for a long touchdown run for the home side.
Los Angeles cornerback Wallace then returned Darnold's initial pick for a big return, leading to a one-yard touchdown by Corum on the ensuing snap.
In the fourth quarter, a touchdown from Matthew Stafford to Puka Nacua extended the Rams' lead to 30-14, but Shaheed provided Seattle's hope with a spectacular punt return.
Darnold then found Barner in the endzone, and a successful two-point play sent the game into an extra period.
Although Nacua raced in for his second TD in overtime, Smith-Njigba responded in kind to setup the game-winning conversion.
