The pitchside announcer might have warned the Molineux faithful to be wary of precarious ice around the stadium but in the end it was their team who slipped up, suffering only their second home league defeat of the season.
And it was an emphatic one at that as Mick McCarthy’s Wolverhampton Wanderers were soundly beaten on a day when the home side’s defensive frailties were as exposed as the freezing temperatures.
To add insult to injury, Wolves – who now have just a four-point cushion between themselves and nearest rivals Reading at the top of the Coca-Cola Championship – saw two of the Lilywhites’ goals come courtesy of former Wolves striker Stephen Elliott.
The 25-year-old Irishman hit a brace to add to a Sean St Ledger headed goal and ensure the spoils went back to Lancashire where Alan Irvine’s side are now also harbouring their own thoughts of promotion.
Elliott’s return to Molineux, just months after he was released by McCarthy, whom he had followed from Sunderland, broke Molineux hearts and cancelled out a 20th-minute strike from the Wanderers’ Mr Reliable Sylvan Ebanks-Blake.
The PFA Player for December was delighted to open the home side’s account to bring his own personal tally this season to 16 goals but would surely have swopped that for a win.
It may have been Preston’s day, however, but it was not all plain-sailing for manager Irvine who was sent to the stands after a bizarre couple of minutes deep in the second half.
Wolves felt they were due a penalty after Jon Parkin appeared to use his arm to clear a loose ball off the line in the 76th minute and Irvine protested by flinging his water bottle on the ground as referee Colin Webster pointed to the spot.
But, like just a week ago when the referee changed his mind to deny Hull City a penalty for a handball against Aston Villa, the Molineux referee suddenly decided to confer with his linesman who immediately urged a change of heart and ruled against a spot kick.
Irvine was already being shooed to the stands as the game re-started, unaware his side was still firmly in the driving seat.
Wolves boss McCarthy was not impressed with the decision against the penalty at the final whistle insisting the claim for a spot-kick was a valid one.
He said: “It was a penalty. I watched it again afterwards and it hit his arm. The referee had the best view of it but the linesman disagreed.
“I am not sure how long was to go by then but that could have made all the difference. “
Preston boss Irvine said: “It was a fantastic result against a very good team.”
And recalling his dismissal, he said: “I threw a water bottle down after the referee had made the penalty decision but that was before he changed his mind!
“I wish now I had kept it in my hand for a little bit longer! It was no where near anyone I just threw it down and I think it made a bit of a dent in the grass.
“It wasn’t as if I hit anyone or injured anyone. It was a bit of fairly controlled aggression!”
The Scotsman contradicted McCarthy’s view on the penalty that never was.
He said: “It was the linesman who had the best view. I can only give you my opinion but I thought Jon Parkin played the ball off his chest.”
