Tight end Saubert made the game-winning two-point play for the Seahawks.
Seattle engineered a stunning comeback to defeat the Los Angeles Rams in overtime, clinching their spot in the postseason.
Rallying from a sixteen-point deficit in the fourth quarter, the Seahawks emerged victorious 38-37 at home, notching their fifth straight victory.
While the Los Angeles had become the first to earn a playoff berth earlier on game day, the Seattle team secured their place to the play-offs after a 24-month absence.
With this outcome, the Seahawks now lead their Conference race with a 12-3 record, supplanting the Los Angeles, who fell to the fifth playoff position with an 11-4 record.
Signal-caller Sam Darnold threw two interceptions but recovered to deliver two touchdown passes, culminating in the second score to wideout Jaxon Smith-Njigba in the extra period.
The Rams held a 13-7 lead at half-time before Kenneth Walker III broke free for a 55-yard scoring dash for the home side.
Rams cornerback Josh Wallace then took back Darnold's first interception for a big return, setting up a short touchdown by Corum on the next play.
In the fourth quarter, a touchdown from Matthew Stafford to Puka Nacua pushed the Rams' lead to 30-14, but Rashid Shaheed ignited Seattle's hope with a 58-yard return for a score.
Darnold then connected with AJ Barner in the endzone, and a converted conversion sent the contest into an extra period.
Although Puka Nacua scored for his second touchdown in OT, Smith-Njigba answered in kind to set up the game-winning score.
