A look at some memorable moments in Seahawks history that occurred on Dec. 15:
1984: The Seahawks officially retired No. 12 to honor their fans. The ceremony takes place during their regular-season finale against the Denver Broncos at the Kingdome. The Seahawks are the first professional sports franchise to retire a jersey as a tribute to their fans. The Seahawks lose 31-14 to finish 12-4, despite Dave Krieg passing for 334 yards and two touchdowns and the defense intercepting John Elway four times.
1985: The Seahawks generate 201 yards of total offense in a 13-3 loss to the Raiders in Los Angeles as Marcus Allen runs for 109 yards and the game's only touchdown.
1991: The Seahawks are shutout in the first half of a 26-13 loss to the Falcons in Atlanta. John Kasay kicks a pair of 43-yard field goals and Dave Krieg throws a touchdown pass in the second half, but it's not enough to offset Deion Sanders intercepting two passes and scoring on a third as he runs 55 yards after taking a lateral from Tim McKyer.
1996: The Jaguars score 13 points in the fourth quarter in pulling out a 20-13 victory over the Seahawks in Jacksonville as Jimmy Smith catches eight passes for 124 yards, including two touchdown passes from former University of Washington QB Mark Brunell.
2002: Shaun Alexander scores on a 27-yard run in overtime to give the Seahawks a 30-24 victory over the Falcons in Atlanta. The Seahawks take a 24-17 lead as Willie Williams returns a fumble 25 yards for a TD and Rian Lindell kicks a 43-yard field goal with 1:55 to play in regulation, but Michael Vick throws a TD pass with 17 seconds left to tie the game. Alexander finishes with 127 yards and two touchdowns, while Koren Robinson catches nine passes for 143 yards.
2013: It what will prove to be a tune-up for Super Bowl XLVIII at MetLife Stadium, the Seahawks intercept Giants QB Eli Manning five times in a 23-0 victory that pushes the Seahawks' record to 12-2. Cornerbacks Richard Sherman and Byron Maxwell each have two interceptions, while Sherman tips a pass in the end zone that is intercepted by Earl Thomas. In their return to MetLife Stadium on Feb. 2, the Seahawks would defeat the Denver Broncos and Peyton Manning 43-8 to win the franchise's first Super Bowl.
