Tight end Eric Saubert made the decisive two-point conversion for Seattle.
The Seattle Seahawks staged a remarkable fightback to overcome the Rams in overtime, securing their place in the postseason.
Overcoming a sixteen-point hole in the fourth quarter, the Seahawks emerged victorious 38-37 at home, notching their fifth consecutive win.
While the Los Angeles had become the first to earn a playoff spot earlier on Sunday, the Seahawks secured their place to the postseason after a two-year hiatus.
With this outcome, the Seattle have taken over their division's race with a twelve and three mark, replacing the Rams, who dropped to the fifth playoff position with an 11-4 record.
Signal-caller Darnold threw two picks but regrouped to deliver two touchdown passes, culminating in the tying score to wideout Smith-Njigba in the extra period.
The visitors held a 13-7 lead at half-time before Walker burst through for a long touchdown run for the home side.
Los Angeles cornerback Josh Wallace then returned Darnold's initial interception for a big return, setting up a short touchdown by Blake Corum on the next play.
In the final stanza, a touchdown from Matthew Stafford to Puka Nacua pushed the Rams' lead to 30-14, but Shaheed provided Seattle's comeback with a 58-yard punt return.
Darnold then connected with AJ Barner in the endzone, and a successful conversion forced the contest into an extra period.
Although Nacua raced in for his second touchdown in overtime, Jaxon Smith-Njigba answered in kind to setup the game-winning conversion.
