Buffalo (5-2) started the season with three high-profile wins, but things have been rough lately. The team's 23-20 win over the New York Jets in Week 6 was a perfect example, with the Bills surviving two Jets Field scoring attempts by a score of 20. A loss in the red zone almost cost Buffalo, but Tyler Bass' late chip a field goal (and an Aaron Rodgers interception by Taron Johnson with less than two minutes to play) got the AFC North leaders back up after two straight losses Course. Last week, the Bills returned with another high-scoring win, defeating the Tennessee Titans 34-10.

The Seahawks (4-3) ended a losing streak of their own last week, completing a three-game losing streak with a 34-14 Week 7 win over the Atlanta Falcons. Seattle was in the lead for most of the game and finally underlined its superiority on the day with a strong second half. Although Atlanta had more offense overall, the Seahawks committed three turnovers, and Seattle's offense, led by veteran Geno Smith (who threw two touchdowns), remained efficient en route to a solid win. However, star wide receiver DK Metcalf is questionable after leaving the game with a diagnosed MCL sprain.
