Kansas City have dominated their rivalry with the Raiders in recent years, but Las Vegas are vastly improved after winning only three games last season and pushed the Chiefs all the way.

The Raiders led 13-10 heading into the final quarter in Vegas, which featured three lead changes before Kansas City held on for a 30-27 win.

The turning point came as new running back Kenneth Walker maintained his stunning start by scoring two touchdowns in 19 seconds, with the Chiefs regaining possession immediately by forcing a fumble on the kick-off return.

The Raiders gave themselves hope with a Brock Bowers score and stayed alive until the final play, when Kirk Cousins was tackled as he threw and his wayward pass was intercepted.

Walker finished with 177 yards from 22 carries, while team-mate Tyquan Thornton also had two touchdowns and 111 receiving yards.

After missing last season’s play-offs, the Chiefs look capable of getting back into Super Bowl contention. They next face the Los Angeles Chargers, who are 0-4 after losing 30-23 to defending champions the Seattle Seahawks.
