Chicago Bears pass-rusher extraordinaire Khalil Mack is unlikely to play in Sunday's game versus the Buffalo Bills due to a sprained ankle, ESPN's Adam Schefter reports, citing a source.
Mack missed the Bears' Week 8 contest against the New York Jets. His availability for Week 9 will be determined after pregame workouts, according to Schefter.
Mack has five sacks, four forced fumbles, an interception, and a touchdown in his six games played with the Bears this season.
