The Buffalo Bills and the Chicago Bears battled in a joint practice prior to their August 17 preseason game, and some suggest that Caleb Williams bested Josh Allen

Caleb Williams and Rome Odunze's connection looks more special every practice. This connection isn't just tearing up the Bears' defense every day, but other defenses in joint practices. What a win it is for Ryan Poles that Rome Odunze, the other first-round draft pick in the same year as Caleb, is becoming his quarterback's right-hand man.

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.

Ben Johnson and staff will be looking for plenty of improvement across the board over the preseason opener but seeing their first-team offense function properly is huge.

Williams will get a dry run on game-week preparation this week against the Bills and next week against the Chiefs ahead of the Sept. 8 opener against the Vikings.

The Chicago Bears will host the Buffalo Bills in a 2025 NFL preseason battle on Sunday. The Bears are coming off a 24-24 tie with the Dolphins, while the Bills lost to the Giants, 34-25, in their first preseason contest.
