Wycombe secured a vital three points in their bid for Championship survival with a 1-0 win over Preston.
In blustery conditions, Ryan Tafazolli's header proved the difference for a Chairboys side who controlled proceedings to earn their sixth victory of the season, while Preston's poor run now stands at one win in seven.
Both sides made two changes from their last outings, with Wycombe eyeing a second win against Preston in the space of three months after their 4-1 FA Cup victory earlier this year.
The opening exchanges belonged to the hosts and Tafazolli showed a glimpse of what was to come as he rose to meet two Joe Jacobson corners. After planting the first effort wide, his second was on target and needed a hand from Daniel Iversen to touch it over the bar.
From the resulting corner, it was third time lucky for Tafazolli as he once again climbed highest to send a firm header across goal and into the net to break the deadlock just before the half-hour mark.
The goal saw Wycombe grow in confidence and Garath McCleary's shot from outside the area was pushed wide by Iversen as they looked to stretch their lead.
At the other end, Preston struggled to carve out any clear-cut chances of their own, with their biggest opportunity coming after David Stockdale flapped at a Preston corner before the ball was cleared.
After a first half in which his side mustered just one shot on target, Preston manager Alex Neil opted for a triple substitution at half-time.
And with the wind behind them in the second half, the changes saw Preston show more attacking intent and Ched Evans curled a shot narrowly over just before the hour mark.
Wycombe continued to create chances of their own and when Dominic Gape found some space down the right, his ball across goal had to be dealt with by Sepp Van Den Berg to avoid a tap-in for Ikpeazu.
There was time for another Preston chance but Potts could only blast wide from a Evans header, and the Chairboys held on for a victory which keeps their dreams of a great escape alive.
