The Kansas City Chiefs extended their winning streak in the NFL, while Kyler Murray inspired the Arizona Cardinals on Sunday.

Patrick Mahomes' Chiefs improved to 13-1 thanks to a hard-fought win over the New Orleans Saints, who welcomed back Drew Brees.

Meanwhile, Murray and Jalen Hurts put on a show as the Cardinals overcame the Philadelphia Eagles.

The Cleveland Browns took another step towards a playoff spot and the New York Jets' wait for a first win came to an end.

CHIEFS TOO GOOD FOR SAINTS AS BREES RETURNS

Mahomes and Brees both threw three touchdown passes as the Chiefs recorded a 32-29 victory.

A ninth straight win helped the Chiefs improve to 13-1, and they are on track to secure the top seed in the AFC.

Mahomes completed 26 of 47 passes for 254 yards and three touchdowns, while he was sacked four times.

The Chiefs became the first team in NFL history to win six straight games by six points or fewer, as per Stats Perform.

Brees, returning from injury, made the worst start of his career by going 0-for-six. He finished 15 of 34 for 234 yards, three TDs and an interception.

The Saints (10-4) are ahead of the Tampa Bay Buccaneers (9-5) in the NFC South.

CARDINALS OVERCOME EAGLES IN THRILLER

Murray helped the Cardinals (8-6) remain on track for the playoffs with a 33-26 victory over the Eagles (4-9-1).

The Cardinals QB was 27 of 36 for 406 yards, three touchdowns and an interception, while also rushing for 29 yards and a TD.

Making his second start, Hurts almost inspired the Eagles to another win, also throwing for three touchdowns and rushing for another.

Murray and DeAndre Hopkins connected on a 20-yard pass with just over seven minutes remaining for what proved to be the game-winning score.

According to NFL Research, Murray is the fourth quarterback in the Super Bowl era aged 23 or younger to throw for 400-plys yards and have a 125-plus passer rating in a game. The previous three (Dan Marino, Jared Goff and Mahomes) reached the Super Bowl in that season.

BROWNS BOOST PLAYOFF CHANCES, JETS WIN

The Browns made it 10 wins in a season for the first time since 2007, brushing past the New York Giants 20-6.

Baker Mayfield starred, completing 27 of 32 passes for 297 yards and two touchdowns.

The Jets' wait for a first win of the season came to an end with an upset 23-20 victory over the Los Angeles Rams.

However, the success hurt the Jets' chances of landing Trevor Lawrence in the draft, with the Jacksonville Jaguars (also 1-13) now in position to get the Clemson Tigers quarterback
