The Seattle Seahawks learned when they will be playing in Week 18 after Sunday's Week 17 games were done. Head coach Mike Macdonald's team already knew that it would be playing the San Francisco 49ers to end the season, just as the two teams met at the beginning of the season.
What Seattle didn't know was when they would take on the 49ers in a game that would ultimately determine the NFC West title and the top seed in the NFC playoffs. In other words, the game is one of the most important in the NFL season.
