Three second-half goals saw Preston North End beaten 3-0 at the home of league leaders Leicester City.
PNE fought well against the title favourites and could have gone into the break ahead if Duane Holmes had managed to get his 43rd-minute effort on target.
North End continued to compete in the second half, but once Kiernan Dewsbury-Hall put his side ahead on the hour mark, the Foxes looked more comfortable, and Kelechi Iheanacho and another from Dewsbury-Hall added gloss to the scoreline.
There were four changes made to the North End side from the weekend, with Ben Whiteman, Greg Cunningham, Jack Whatmough and Robbie Brady coming into the starting XI, and there was a change of shape too with Ryan Lowe opting for a four at the back.
PNE started brightly and had an early attack down the left through Brady, while the hosts soon started to see the lion’s share of the ball, although with few chances to show for it.
Liam Lindsay won two important headers on the six-yard line ahead of Jamie Vardy within the opening ten minutes, before then getting in the way of a close-range Dewsbury-Hall effort, following good skill from former PNE man Stephy Mavididi.
North End enjoyed their best move yet in the 26th minute which culminated in Potts sending a dangerous, low cross into the area which defender Wout Faes hit against the back of his own goalkeeper, and on another day it may have rebounded into goal, but Leicester managed to get to the second ball and clear.
Holmes had the biggest chance of the match so far for PNE two minutes before the break when he was slotted into the area by Ali McCann, however the US international sent a low strike wide of the near post.
North End more than matched the title favourites in the first half and had the first chance of the second, which saw Brady have a shot deflected behind, before Holmes was again involved in the 57th minute, forcing Mads Hermansen into a smart diving save.
The hosts went ahead on the hour mark, though, as McCann’s attempted interception redirected the ball into the path of Dewsbury-Hall who slotted past Freddie Woodman.
Substitute Iheanacho then made it two in the 76th minute on the end of a good one-touch move involving Dewsbury-Hall and Wilfred Ndidi.
Ben Woodburn – part of a triple change just after that goal – found the back of the net for his side soon after his introduction, but he was ruled to have brought down Faes while winning the ball back.
In the final minute of the 90, Woodman came up with a superb stop to deny Iheanacho, but the follow-up was finished off by Dewsbury-Hall.
