Kansas City Chiefs quarterback Patrick Mahomes said Monday's 30-29 win over the Las Vegas Raiders was a result that would "build the true character" of the team.

The AFC West outfit edged a thriller against their divisional rivals at Arrowhead Stadium to move to 4-1 for this NFL season, fighting back from a 17-point deficit midway through the second quarter.

Four touchdowns for tight end Travis Kelce saw the hosts complete a remarkable comeback, while the Raiders fluffed a two-point attempt to win the match in the closing minutes.

The result came amid another controversial roughing call, when Chris Jones was penalised amid a strip on Derek Carr, and Mahomes suggested his side's frustration helped fire them on to another victory.

"Sometimes, these games are the ones that build the true character of the team," he said. "How you respond, go back and fight, that was good to see from this team.

"It wasn't the greatest call in the world. You have to find a way to bounce back and we did."

Official Carl Cheffers was lambasted by Chiefs coach Andy Reid following the call, and as the teams headed into the half-time interval, but the latter stated he had said his piece when pressed post-game.

"I got it off my chest," Reid said. "I said what I needed to say."

The Chiefs will welcome the Buffalo Bills to face them on Sunday as they look to keep their hand atop AFC West, while the Raiders will cool their heels for a fortnight before facing the Houston Texans.
