The victory for Preston sees them sit 13th in the Championship table, meanwhile Huddersfield are currently sitting in 19th and under serious threat from relegation.
Here are some conclusions to take out of the result.
Daniel Iversen is an excellent signing
Preston North End bolstered their squad in January with some excellent signings, such as Anthony Gordan and Sepp Van Den Berg who were both impressive today. But a signing that seemed to go under the radar last month was the loan capture of Danish goalkeeper Daniel Iversen, who put in an exceptional performance on Saturday.
Former Huddersfield target Iversen was exceptional in the Lilywhites goal and made some excellent saves including denying Isaac Mbenza from what would have been a stunning free kick strike.
The Dane has already established himself as the first choice at Deepdale after an injury to Declan Rudd and it's becoming quite clear that he's an excellent singing for the Lancashire side.
The penalty shout was the turning point
The turning point in yesterday's encounter proved to be a huge penalty shout for Huddersfield, that was ultimately not given by the referee.
With the game at 0-0 and Huddersfield looking the better side, Preston's Andrew Hughes tangled with Huddersfield's Fraizer Campbell in the box. The Huddersfield attacker subsequently protested for a penalty but was turned away by the official.
While a penalty may have been harsh there was undoubted contact between the defender and the attacker, and the decision was a key factor in Huddersfield's demise with Brad Potts subsequently giving the hosts the lead shortly after.
Sanogo makes his Huddersfield debut
Perhaps the only positive Huddersfield can take out of their miserable display was the debut of Frenchman Yaya Sanogo, who arrived in West Yorkshire earlier this week as a free transfer.
The former Arsenal striker came off the bench for the last 15 minutes and showed brief glimpses of quality, in what was a challenging situation to make your debut.
As Sanogo's fitness continues to build, he will soon be in a position where he's able to start for Huddersfield and will bring much needed impetus to the Terriers' frontline.
Huddersfield now in the thick of a relegation fight
A week can change a lot in football and so it's proved for Carlos Corberan's Huddersfield Town.
After a convincing victory against Swansea City last week it seemed like Huddersfield had turned a corner and would be able to build on the momentum of that victory.
The Terriers have slipped back into their bad habits however, and are now very much in the thick of the relegation battle at the foot of the Championship table. This will prove to be a huge concern to Carlos Corberan and his players, who are struggling to find victories so far in 2021.
Ultimately, Preston were by far the better side at Deepdale, and were well worthy of their victory in Lancashire.
The biggest refereeing decision of the game went against the Terriers with their claims for a penalty turned away, and from that point North End took control of the match and punished Huddersfield who were lacklustre.
While Preston seem to be heading towards a mid table finish, Huddersfield are continuing their bad habits and are are now a side in great threat from relegation.
