A solitary goal from Jermaine Beckford, his first for the club, was enough to see Preston clinch victory over the home side whoa re again chasing a play off spot.
Preston remain in fourth place but both Bristol City and Swindon lost on Saturday meaning that the gap to the leaders is now just one point with MK Dons the other side who are in the mix for the top two spots at the moment.
The Whites now face Barnsley at home on Boxing Day before travelling to Crewe only 48 hours later. If Preston could pick up six points from these two fixtures then they would head into the new year with confidence.
