The Kansas City Chiefs defeated the Washington Redskins, 29-20, to remain undefeated on Monday night at Arrowhead Stadium.

With the game tied at 20 points apiece and less than a minute remaining in regulation, rookie kicker Harrison Butker connected on a 43-yard field goal to win the game for Kansas City.

It was the rookie kicker's first-career game.

Chiefs' quarterback Alex Smith led Kansas City 50 yards in just six plays to set up Butker's game-winning kick.

With just four seconds remaining following Butker's kick, linebacker Justin Houston picked up a Redskins' fumble and ran it in for the touchdown as time expired. 

Smith completed 27 of 37 passes for 293 yards and a touchdown while running for another score on the night.

The Chiefs found themselves facing an early ten-point deficit before Smith found tight end Travis Kelce for Kansas City's first score of the game in the closing minutes of the first half.

The two teams traded leads throughout the second half before Butker's kick sealed the victory for Kansas City.

Kelce led all receivers with seven catches for 111 yards in the game.

Rookie running back Kareem Hunt continued his torrid start to his career, running for 101 yards on 21 carries while hauling in four passes for 20 yards through the air. He tallied 121 total yards from scrimmage, joining LaDainian Tomlinson, Adrian Peterson and Billy Sims as the only players to notch 100-plus yards from scrimmage in each of their first four games since 1950.

The Chiefs will look to continue their winnings ways next week as they travel to Houston to take on the Texans.
