Looking for their first 2-0 start since 2014, the Bills traveled to Bank of America Stadium for an inter-conference matchup with the Panthers. Many former Panthers players and personnel made their return to Carolina as members of the Bills, including fullback Mike Tolbert, cornerback Leonard Johnson, wide receiver Kaelin Clay, general manager Brandon Beane and head coach Sean McDermott. Unfortunately, despite the defense sacking Panthers QB Cam Newton six times and only allowing three field goals from Graham Gano, the Bills offense couldn't take advantage, only managing a 45-yard field goal from Steven Hauschka in the fourth quarter, the team's lowest points since losing 45-3 to the San Francisco 49ers in 2012. A potential game-winning touchdown pass from QB Tyrod Taylor to rookie WR Zay Jones on 4th-and-11 with 0:09 remaining sailed off Jones' fingertips, putting the game away for the Panthers. The Bills fell to 1-1 with the loss.
