Reigning NFL Most Valuable Player Josh Allen and the Buffalo Bills suffered a surprise defeat for the second consecutive week, falling 24-14 in Atlanta on Monday.
Michael Penix threw for 250 yards and a touchdown while Bijan Robinson ran 19 times for 170 yards and a touchdown to spark the Falcons attack.
Robinson, who also caught six passes for 68 yards, said: “This was a big game for us.
“We had to come out and be physical. We do what we do and come out with a win.”
Allen threw for 180 yards and two touchdowns but also two costly interceptions as the Bills slid to 4-2 and level for the AFC East division lead with New England, which upset Buffalo 23-20 last week.
The Falcons improved to 3-2 and moved into second in the NFC South.
