Entering the bye week atop the AFC East (though thanks to tiebreakers), it has been a bit of the good the bad and the ugly for the Buffalo Bills.

Coach Sean McDermott said he believes this time off is huge for them in the terms of evaluating what they've done and what they can do going forward.

"We've got to look at everything. It's never just one thing. It's never just the offensive line. Never just tight ends. Never just the wide receivers and the eight man box. It's all of that. It's everything we can do better. This week being our bye, it's about self-awareness and what we've done well and what we haven't well, and also looking to evolve and that's the important part as we look at what's in front of us this week," he said.

On the injury front, Charles Clay underwent left knee surgery and will be out multiple weeks, according to McDermott. The tight end and team's top pass catcher suffered a torn meniscus and sprained MCL in the first quarter of Sunday's loss in Cincinnati, according to Pro Football Talk.

Nick O'Leary is expected to slide into the top tight end roll after leading the Bills with 54 receiving yards on a career-high five catches in the loss

"I thought Nick did a good job yesterday in the passing game. He made some key catches for us and he's a guy that Tyrod [Taylor] trusts, and he's made some big plays for us so far this year and I like the direction he's headed right now," McDermott said.

O'Leary has 7 catches for 107 yards on the season.
