One of the biggest preseason delights for Chicago has been defensive end Austin Booker, who has four sacks already. After picking up his fourth sack of the preseason in this game against Buffalo, Booker met with the medical staff and then was later ruled out with a knee injury.

The Bears host the Bills in NFL preseason action at 8 p.m. ET on FOX, with Chicago's starters expected to take the field.

This is not a nationally broadcast game, but it can still be live-streamed locally on Fubo through KCBS-CBS2 (Los Angeles) or KABC-ABC (Los Angeles). It will be aired via tape delay later on NFL Network.
