Khalil Mack has never missed a game since entering the league in 2014. Will Week 8 of the 2018 season be the first?
The Bears' outside linebacker was limited in practice Friday and is listed as questionable for Sunday's game against the New York Jets. Mack, who sat out the previous two practices, has been playing through an ankle sprain that he suffered two weeks ago.
Since then, Mack has not recorded a sack while recording just three tackles altogether.
Chicago might also be without receiver Allen Robinson (groin), who is listed as questionable. Left guard Eric Kush (neck) has been ruled out.
