It hurt more than any defeat in recent years.
The result many dreaded and were praying wouldn't happen - Preston North End losing Saturday's Lancashire derby at Bloomfield Road against Blackpool.
It was as deflating and painful as it gets for North End fans, with plenty said in light of the derby day disaster and it an afternoon that won't be forgotten for a long old time - for all the wrong reasons.
But for the squad, who you would expect to feel that agony too, it is a negative they simply can't afford to still have in their system when Liverpool come to town in 48 hours.
Sean Maguire said on Monday morning that he and his team-mates must use it as fuel.

Anyone connected with PNE, who tuned into Sky Sports at 4:30pm on Sunday afternoon, will have firstly laughed at Manchester United's expense.
Then, as a reminder of Wednesday's televised cup tie popped up at the bottom of the screen, the realisation hit that this unstoppable footballing machine would be on Deepdale turf next.
Granted that Mohamed Salah, Virgil van Dijk, Trent Alexander-Arnold and co will likely get the night off, but Liverpool's 'second-string' thumped Norwich in the previous round three-nil
The quality in Jurgen Klopp's squad is off the scale, so whichever 11 players Frankie McAvoy picks, they will know the almighty challenge that awaits.
If the Scot's men go into the cup tie feeling sorry for themselves or allow the understandable apathy from supporters to creep into the dressing room, make no bones about it, Liverpool will run riot.
McAvoy will go through the Blackpool game with his squad today (25/10) at Euxton.
It will be tough for those players to watch after a Sunday most-likely spent trying to think about anything else.
But once that video finishes and the team meeting concludes, it it then a mental test as to whether the group can pick themselves out of the gutter and go again.
Klopp's Reds will show no sympathy whatsoever and while a spirited PNE performance won't right the weekend's wrong, it wouldn't half be better than a sell-out Deepdale witnessing a drubbing.
