Stephen Hauschka kicked a tiebreaking 56-yard field goal with less than 5 minutes remaining and the Buffalo Bills made a last-minute defensive stand to beat Atlanta 23-17 on Sunday after the Falcons lost wide receiver Julio Jones to a hip injury.
Hauschka padded the lead with a 55-yarder with about 3 minutes remaining.
Buffalo's defense stopped the Falcons at the Bills 10 with less than a minute remaining when Matt Ryan could not complete a fourth-down pass to Taylor Gabriel, and Atlanta became the last NFC team to lose this season.

It was one of three turnovers by Atlanta (3-1) on a day the Bills (3-1) set a team record for consecutive quarters without a turnover. Ryan threw two interceptions, giving him five in his last two games.
Jones left the game in the second quarter with a hip flexor injury and did not return. Atlanta's receiving corps took another hit when starter Mohamed Sanu was ruled out with a hamstring injury in the third quarter.
