A look at some memorable moments in Seahawks history that occurred on Dec. 21:
1997: Warren Moon passes for four touchdowns as the Seahawks finish 8-8 by slapping the playoff-bound 49ers with a 38-9 loss in the season finale at the Kingdome. Joey Galloway catches six passes for 101 yards and two scores, while Mike Pritchard has six receptions for 90 yards and a TD. The linebacking crew of Mike Barber, Chad Brown and Dean Wells leads the defensive effort by combining for 25 tackles.

2003: Shaun Alexander runs for 135 yards and two touchdowns, including a 44-yarder, and the defense sacks Cardinals QB Josh McCown eight times in a 28-10 victory in Seattle.
2008: The Seahawks send Mike Holmgren out a winner in his final home game as coach with a 13-3 victory over the Jets on a snowy afternoon in Seattle. Maurice Morris runs for 116 yards and Seneca Wallace passes to John Carlson for the game's only touchdown, while Josh Wilson interceptions Brett Favre twice.
