Swansea City shocked Nottingham Forest with a stunning late comeback to progress to the last 16 of the Carabao Cup and keep Ange Postecoglou waiting for his first win in charge of the visitors.
Forest had looked like they were set for a comfortable victory after Igor Jesus' first-half double put them in command.
But, having already got back into the tie via Cameron Burgess, Zan Vipotnik in injury time struck to seemingly send the game to penalties.
Yet more drama was to come as Australia international Burgess fired home from just inside the area to send Forest out and Swansea into the last 16.
His compatriot Postecoglou had to watch as the visitors threw victory away to exit a competition that provided the club's last major silverware in 1990.
Conversely, Swansea – League Cup winners in 2013 – enjoyed their finest cup success since relegation from the Premier League.
That seemed far away when Forest, having made 10 changes from the defeat by Arsenal in Postecoglou's first game in charge, took control via Jesus' first goals since his £10m summer move from Botafogo.
The first came after 15 minutes when after a driving run from the left, Hutchinson's shot hit an unsuspecting defender and into the path of Jesus. Squeezing his shot in from the far post, it was the Brazil international's first goal since his winner against Paris St-Germain at the Club World Cup.
Swansea carried greater urgency, but not the threat and the tie looked effectively settled in the final moments of the first half as clever work from James McAtee down the Forest right picked out Hutchinson who provided a tap-in for Jesus.
Burgess' glancing header from Eom Jisung's corner gave Swansea hope and raised noise levels that exploded when Vipotnik turned home Liam Cullen's cross three minutes into stoppage time.
And any hopes of penalties saving Postecoglou from embarrassment were denied by Burgess rifling home as Forest failed to clear a corner in the seventh additional minute.
