Fresh off their bye week, the Bills returned home to host the Tampa Bay Buccaneers. LeSean McCoy scored his first two touchdowns of the season as the Bills won a shootout match 30-27, with their final 10 points coming in the last three minutes of the game. With Tampa Bay taking the lead after forcing McCoy to fumble and capitalizing with a Mike Evans touchdown pass from Jameis Winston, Tyrod Taylor led the Bills 75 yards downfield, connecting with newly signed receiver Deonte Thompson for 44 yards to help set up McCoy's second touchdown. Tre'Davious White then forced the Buccaneers to fumble on their ensuing drive, setting up Steven Hauschka's game winning field goal. The Bills improve to 4-2 with the win. Note: Former Bills Garrison Sanborn and Ryan Fitzpatrick made their first return to New Era Field since signing with the Buccaneers in free agency.
