Input (English): Passage: After losing a heartbreaker in Cincinnati to the Bengals, the Seahawks returned home to face their second undefeated team in a row, the 4-0 Carolina Panthers. With 11:51 remaining in the 4th quarter, the Seahawks led the Panthers, 23-14. However, for the fourth time this season, the Seahawks failed to win while holding a 4th quarter lead. The Panthers went on to score the final 13 points of the game, winning 27-23.

Up to this point, they were in 3rd place in the NFC West (due to tiebreakers).
