Scott Parker’s 71st-minute introduction of Sporting loanee Marcus Edwards saw Anthony moved over to the left and the on-loan Bournemouth man nearly made an instant impact on the opposite flank, shifting inside of Ryan Porteous before bending a shot just over the top.
Burnley had the first glimpse of goal after seven minutes but Jaidon Anthony dragged his shot wide upon entering the box after doing well to dispossess Jayden Meghoma.
Foster, however, should have fired Burnley ahead in the final seconds of the half, after being teed up on a plate by Flemming, but the 24-year-old sent his effort from the centre of the box into orbit with the goal gaping.
But Preston quickly rallied and caught their opponents cold just three minutes later as Mads Frøkjær-Jensen slipped Milutin Osmajic in behind and the Montenegrin would have scored had CJ Egan-Riley not recovered well to bravely block.
Just before the half-hour mark it was Egan-Riley’s defensive partner, Maxime Esteve, who was on last-ditch blocking duties, this time to deny Kaine Kesler-Hayden at the far post as the on-loan Aston Villa man tried to provide the finishing touch to a wonderful bit of team play.
