The Chiefs have suffered their first defeat of the Super Rugby Pacific season, after a shock 25-22 loss to Queensland Reds at New Plymouth.
A late penalty goal by replacement Tom Lynagh gave the visitors their first win over the Chiefs on New Zealand soil since 2013.
The Chiefs looked to have crashed over for the game-winning try deep into added time, but were held up, sending the Reds into a frenzy after the final whistle.
In Super Rugby's return to New Plymouth, early signs suggested the script was already written for another Chiefs' victory.
New Plymouth Boys High School alumnus Bradley Slater was at the forefront of his side's early moves, which saw winger Etene Nanai-Seturo cross for the game's first try.
After fullback Shaun Stevenson connected with Slater, the hooker showed tremendous awareness to turn his back to the defence and shift the ball on, allowing an unmarked Nanai-Seturo to slide over in the corner.
But the Reds hit back just minutes later, with prop George Blake crashing over from short-range to lock the scores up at 5-5.
Much of the first half proved to be a surprising back-and-forth arm-wrestle, with the Chiefs unable to capitalise on the Reds' set-piece woes.
The visitors boasted the best lineout of any team entering the fixture, but several overthrows let the Chiefs off the hook, with four inside the opening 30 minutes.
The Chiefs lost All Blacks lock Josh Lord to a head injury, but replacement Manaaki Selby-Rickit made up for the setback with a try-saving tackle on James O'Connor.
O'Connor looked certain to score after he was put into space, but the lock never gave up the pursuit and eventually dragged him down from behind.
That tackle saw a 14-point swing, with an overly excited Reds side guilty of throwing a loose pass, which Nanai-Seturo made sure to make them pay.
He hacked through the ball, before showing great composure to pick up and stroll in for his second try.
But much like earlier in the game, the Reds hit back immediately once more, with halfback Tate McDermott breaking away from a maul to crash over and lock the scores up at 12-all at halftime.
With an entirely new front row on for the second half, the Reds finally found some success with their set piece, needing just a few minutes to grab another try.
Fullback Jock Campbell was the beneficiary of a huge overlap, following several strong surges by the Reds' forwards.
McKenzie ate into the Reds' lead with a penalty goal, but the opposition's replacements refused to budge, with substitute Zane Nonggorr crashing over for his first try in Super Rugby.
With time ticking, Samipeni Finau put an earlier knock behind him to go over for a five-pointer and set up a nervy final few minutes for both sides.
After Lynagh put the Reds back in front with a penalty goal, the Chiefs went the length of the field to almost snatch victory.
But after more than 20 phases and penalty advantages, the Chiefs were held up over the tryline, with the Reds completing an unlikely upset at Yarrow Stadium.
Chiefs 22 (Nanai-Seturo 2, Finau tries; McKenzie 2 con, 1 pen) Reds 25 (Blake, McDermott, Campbell, Nonggorr tries; Creighton 1 con, Lynagh 1 pen)
