The Seattle Seahawks kept the pressure on NFC West leader the San Francisco 49ers with a clinical win over the Buffalo Bills.
The Bills, playing their annual game in Toronto, were in touch at half-time, trailing 31-17 after the first two quarters.
However, the Seahawks' defense prevented Buffalo from adding to their score for the remainder of the tie.
Russell Wilson and Marshawn Lynch led the Seahawks offense, quarterback Wilson with three rushing touchdowns and one touchdown pass.
The Seahawks can close the gap to the 49ers when the two sides meet next weekend, although Seattle remain in contention for a wildcard place in the playoffs if they do not win their division.
