With the Minnesota Vikings (5-3) losing Thursday night, the Bears have a chance to establish at two-game lead in the NFC North on the Vikings, losers of two of their last three, playing well in none of the three and giving up 36 points in each of the two losses.
Detroit (2-4) has Seattle (4-3) in Ford Field in a game that could exacerbate the growing pressure on Lions coach Jim Schwartz, in danger of spiraling to his third losing season in four.
The Bears and Atlanta Falcons are the only NFL teams on streaks of at least four wins; Atlantas is at six with the undefeated start and is at Philadelphia. Even though it will be another two months before it matters, if the Bears win and Falcons lose, the Bears will hold the No. 1 seed in the NFC by virtue of a 4-1 conference mark to Atlantas 2-1.
