Looking to continue their winning ways after upsetting the Falcons the week prior, the Bills traveled down to Cincinnati to take on the Bengals, who got their first win of the season when they defeated their rival Cleveland Browns 31-7 the previous week. Already missing wideout Jordan Matthews, the Bills offense sputtered for the most part after tight end Charles Clay suffered a knee injury in the second quarter and was ruled out the rest of the game. The Bengals rallied behind strong performances from quarterback Andy Dalton and receiver A.J. Green despite the duo committing three turnovers, and won a close-fought game in the rain 20-16. With the loss, Buffalo falls to 3-2 going into their bye week.
