The Cincinnati Bengals reached their first Super Bowl since 1989 after a pulsating 27-24 overtime win against the Kansas City Chiefs in Sunday's AFC Championship Game.

Patrick Mahomes had started in inspired form at Arrowhead Stadium, delivering three touchdown passes to put the Chiefs 21-3 ahead, but the Bengals roared back in stunning fashion to move 24-21 in front.

A Harrison Butker field goal with three seconds left took the game to overtime, yet Evan McPherson ensured a memorable win for the Bengals with a field goal of his own.  

They will face either the Los Angeles Rams or the San Francisco 49ers in Super Bowl LVI in a fortnight.

Mahomes wasted little time in stamping his authority on the game, picking out Tyreek Hill in the end zone for a 10-yard touchdown within the opening three minutes.

McPherson got the Bengals on the board with a field kick soon after, yet the Chiefs extended their advantage when Mahomes danced his way out of trouble to find Travis Kelce in the corner of the end zone.

The irrepressible Mahomes then found Mercole Hardman wide open for another touchdown, taking his total of pass touchdowns in this postseason to a record-equalling 11.

The Bengals, however, clawed their way back into the game when running back Samaje Perine raced 41 yards into the end zone.

McPherson reduced the deficit with another field goal, before B.J. Hill intercepted an uncharacteristically poor throw from Mahomes to give the Bengals an opportunity to draw level. They duly did courtesy of Ja'Marr Chase from Joe Burrow's lofted throw, with Trent Taylor grabbing the subsequent two-point conversion reception.

After McPherson and Butker exchanged field goals in the fourth quarter, the former sent another kick between the sticks following Vonn Bell's interception of Mahomes to seal one of the most remarkable comebacks in Championship Game history.
