The Kansas City Chiefs staged a thrilling comeback from 24-0 down to beat the Houston Texans 51-31 to advance to the AFC Championship game.

Chiefs’ Patrick Mahomes threw for four touchdowns in the second quarter to overhaul the Texans’ early lead.

Kansas scored 41 unanswered points and dominated the second half.

The second seeds now host the Tennessee Titans, who beat the Baltimore Ravens in the other AFC divisional game, for a place at Super Bowl 54.

“We didn’t start the way we wanted to – we just had to keep fighting, just go one play at a time,” quarterback Mahomes said.

“We know the Titans are a tough team we will have to play our best and find a way to win.”

On team-mate Travis Kelce, who he passed to for three touchdowns despite the tight end struggling with a hamstring injury, Mahomes said: “Travis was amazing, man he’s a monster.

“The way he came through injury and was still making plays all day long – he’s a special football player.”

Texans quarterback Deshaun Watson connected with Kenny Stills and Darren Fells and Lonnie Johnson ran in a blocked punt as the visitors raced into a 21-point first-quarter-lead.

But a Damien Williams touchdown five minutes into the second quarter sparked a Chiefs resurgence, with Mahomes finishing with five touchdown passes, 321 passing and 56 rushing yards.

The Texans stopped the rot with the Chiefs leading 41-24 in the third quarter as Watson scored a five-yard rushing touchdown to get the margin within 10.

But the Chiefs extended their lead, Blake Bell adding another touchdown, to leave them one game away from their first Super Bowl appearance since 1970.
