Duane Holmes struck twice as Huddersfield shredded the Championship’s form guide to win for the first time this year.
A barren start to 2021 had seen the Yorkshire club plunge towards the division’s relegation zone but a sizzling 10-minute spell at the start of the second half checked that and condemned promotion-chasing Swansea to a first league defeat in more than two months.
To compound the misery for Steve Cooper’s team, they were forced to play out the final half hour with 10 men following an horrific injury to on-loan American forward Jordan Morris.
Cooper had reacted to Huddersfield’s three-goal salvo at the start of the second period with a triple substitution - having also made two changes at the interval - and Swansea were therefore left undermanned for the final third of the contest when Morris collapsed in a heap attempting to take a ball down the left channel in his stride.
