Chiefs, 49ers advance to Super Bowl showdown

LOS ANGELES - Patrick Mahomes ended the Kansas City Chiefs' 50-year wait for a return to the Super Bowl on Sunday as the San Francisco 49ers routed the Green Bay Packers to advance to next month's NFL showpiece.

Mahomes helped the Chiefs overturn a 10-point deficit to complete a convincing 35-24 win over the Tennessee Titans to take the American Football Conference Championship at Arrowhead Stadium.

The reigning NFL MVP threw for three touchdowns and danced into the end zone for a superb individual score as the Chiefs successfully neutralised the threat posed by Titans running back Derrick Henry.

It is the first time the Chiefs have advanced to the Super Bowl since their victory over the Minnesota Vikings in 1970.

"I'm lucky to be a part of this team with all these guys it makes my job a lot easier," said Mahomes, who finished with 294 passing yards and 23 completions.

The win came one year after the Chiefs suffered an agonising home overtime loss to the New England Patriots at the same stage of the playoffs.

"It's amazing, to be here to do it at Arrowhead, these people deserve it. We're not done yet," Mahomes added. "We're going to get it."

Mahomes said the Chiefs -- who had fought back from 24-0 down to rout the Houston Texans in the divisional round last week -- had kept their cool after falling behind early on against the Titans.

"We just stayed with the process. It was like last week, we just stuck with the game plan and knew it was going to work out," he said.
