Receiver Eric Saubert made the game-winning two-point play for Seattle.
The Seattle Seahawks engineered a stunning comeback to overcome the Rams in overtime, clinching their spot in the NFL play-offs.
Rallying from a sixteen-point hole in the fourth quarter, the Seahawks emerged victorious 38-37 at home, registering their fifth consecutive victory.
While the Los Angeles had already secured a post-season berth earlier on game day, the Seahawks secured their place to the postseason after a 24-month hiatus.
With this outcome, the Seattle now lead their Conference standings with a 12-3 record, replacing the Los Angeles, who fell to the number five playoff position with an eleven and four standing.
Quarterback Darnold threw two interceptions but regrouped to make two touchdown passes, including the second score to wideout Jaxon Smith-Njigba in overtime.
The visitors held a six-point advantage at the break before Kenneth Walker III burst through for a 55-yard touchdown run for Seattle.
Los Angeles defensive back Josh Wallace then took back Darnold's first interception 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 Nacua pushed the Rams' lead to 30-14, but Shaheed provided the comeback with a 58-yard punt return.
Darnold then found AJ Barner in the end zone, and a converted two-point play sent the contest into an extra period.
Although Puka Nacua raced in for his another TD in overtime, Smith-Njigba responded in kind to set up the game-winning score.
