The Kansas City Chiefs will meet the Philadelphia Eagles in the Super Bowl after respective victories over the Cincinnati Bengals and San Francisco 49ers on Sunday.

Patrick Mahomes and the Chiefs secured a trip to their third Super Bowl in four years by escaping a valiant Bengals outfit 23-20.

The Kansas City quarterback had a typically stellar showing, finishing with two touchdowns and 326 passing yards, while his opposite number Joe Burrow threw for a touchdown and two interceptions.

Two early field goals gave the home side an edge, but the Bengals were able to keep in touch through a field goal of their own.

The Chiefs again threatened to pull away when Mahomes found Travis Kelce in the end zone, however another field goal from Bengals kicker Evan McPherson ensured Cincinnati were only behind by seven at half time.

They then drew even at the start of the third courtesy of a 27-yard touchdown to Tee Higgins.

Kansas City responded in kind, Marquez Valdes-Scantling finding the end zone to make it a 20-13 scoreline headed into the fourth quarter.

A two-yard touchdown run from Bengals running back Samaje Perine again drew the scores level, but Harrison Butker's third field goal of the night with just three seconds left on the clock ultimately sealed a thrilling victory for the Chiefs.

Meanwhile, the Eagles had a much easier day at the office, cruising past the 49ers 31-7.

A pair of rushing touchdowns from Miles Sanders helped the Eagles soar past the 49ers in the NFC Championship game after injuries hit quarterback Brock Purdy and backup Josh Johnson.

The evening turned disastrous almost immediately for San Francisco as Pro Bowler Sanders drew first blood with a six-yard run to the end zone in the opening series and Purdy exited the game with an elbow injury on the Niners' first possession.

Running back Christian McCaffrey broke through a swarm of defenders to put the Niners on the board in the second quarter but Sanders wrested the lead back immediately with a 13-yard touchdown.

Johnson, the Niners' fourth-string quarterback after injuries previously sidelined starters Jimmy Garoppolo and Trey Lance, fumbled the ball late in the second quarter and the Eagles recovered, sending a shiver of despair through the away team as Boston Scott ran it into the end zone.

Purdy was forced back into the contest after Johnson smacked his head on the turf but was ineffective against the razor-sharp Eagles, as quarterback Jalen Hurts leapt into the end zone for a touchdown in the third quarter and Jake Elliott made a 31-yard field goal in the fourth.
