Receiver Saubert executed the decisive two-point conversion for the Seahawks.
The Seattle Seahawks staged a remarkable fightback to defeat the Rams in extra time, clinching their place in the NFL play-offs.
Rallying from a sixteen-point hole in the final period, the Seahawks triumphed by a single point at home, registering their fifth consecutive win.
While the Rams had become the first to earn a post-season spot earlier on game day, the Seahawks booked their return to the postseason after a two-year hiatus.
With this result, the Seahawks now lead their Conference standings with a 12-3 mark, supplanting the Rams, who fell to the fifth playoff position with an 11-4 record.
Quarterback Sam Darnold had two picks but recovered to deliver two scoring throws, culminating in the second score to star receiver Smith-Njigba in overtime.
The Rams held a 13-7 lead at the break before Walker burst through for a long touchdown run for Seattle.
Rams defensive back Wallace then returned Darnold's first interception for a big return, setting up a one-yard touchdown by Corum on the next play.
In the final stanza, a touchdown from Matthew Stafford to Nacua pushed the Rams' lead to sixteen points, but Shaheed provided Seattle's comeback with a spectacular return for a score.
Darnold then found Barner in the end zone, and a successful conversion sent the contest into overtime.
Although Nacua raced in for his second TD in overtime, Jaxon Smith-Njigba responded in kind to setup the game-winning conversion.
