Tight end Saubert made the decisive two-point play for the Seahawks.
Seattle engineered a stunning comeback to defeat the Los Angeles Rams in extra time, securing their place in the NFL play-offs.
Overcoming a sixteen-point hole in the final period, the Seahawks emerged victorious 38-37 at home, notching their fifth consecutive victory.
While the Rams had become the first to earn a post-season berth earlier on game day, the Seattle team secured their place to the play-offs after a 24-month absence.
With this outcome, the Seattle have taken over their Conference race with a twelve and three record, supplanting the Los Angeles, who fell to the fifth seed with an eleven and four record.
Signal-caller Sam Darnold threw two picks but recovered to make two touchdown passes, including the second score to star receiver Smith-Njigba in the extra period.
The visitors held a 13-7 advantage at half-time before Walker broke free for a 55-yard scoring dash for Seattle.
Los Angeles defensive back Josh Wallace then returned Darnold's first pick for 56 yards, setting up a one-yard touchdown by Blake Corum on the ensuing snap.
In the fourth quarter, a touchdown from Matthew Stafford to Puka Nacua pushed the Rams' lead to 30-14, but Shaheed ignited Seattle's comeback with a spectacular return for a score.
Darnold then connected with AJ Barner in the endzone, and a converted conversion forced the game into an extra period.
Although Nacua scored for his another touchdown in overtime, Smith-Njigba answered in kind to set up the decisive conversion.
