Chicago Bears linebacker Khalil Mack (ankle) did not practice on Wednesday.
Mack has been hobbled by an ankle injury he suffered in Week 6 and was unable to play or practice last week. At this point, it is unclear if Mack will be active for Sunday's game against the Bills but the Bears defense should dominate against a Buffalo offense rated 32nd overall by numberFire's power rankings.
Heading into Week 9, the Bears defense is ranked seventh overall by our models.
