The Raiders hung with the Bills. The game was tied 13-13 at halftime and 23-23 in the fourth quarter.
It never felt like the Bills were in danger of losing, though the Raiders never went away.
Josh Allen led Buffalo to a 33-30 win in Las Vegas as the Bills moved to 5-1. The Raiders fell to 3-3.
The Bills gained 345 yards, with 169 coming in the second half when they scored 20 points.
Allen was 23-of-33 for 255 yards and two touchdowns, including a Houdini-esque 12-yard touchdown pass to Keon Coleman on third-and-8 in the fourth quarter.
James Cook's 3-yard touchdown run with 4:43 left was the go-ahead score, with Tyler Bass adding a 38-yard field goal with 1:56 remaining.
Bass also made kicks from 44, 28 and 47.
Coleman caught four passes for 59 yards and a touchdown, and Cook had 22 carries for 95 yards and a touchdown.
The Raiders made it interesting on Kirk Cousins' 44-yard touchdown throw to Tre Tucker with 1:32 left.
The Raiders, though, didn't have a prayer of recovering the onside kick, something they haven't done since 2017 against the Chiefs. Matt Gay kicked a drop kick too far, and Khalil Shakir caught it in the air.
Cousins finished 23-of-41 for 313 yards with two touchdowns and an interception. Tucker had five catches for 97 yards and two touchdowns, and Michael Mayer added seven receptions for 95 yards.
