It was always thought that Preston would play everton at Deepdale but the possible date, a week prior to the start of the season has been changed due to Everton going on a pre-season tour to the States.
Preston will play Everton in midweek on Tuesday 22 July which will be followed up with the confirmed game at Carlisle the following Saturday.
This adds to the already confirmed games against Bamber Bridge and Chorley along with the training camp to Austria. It does leave Preston with a problem of who they will play for a final friendly game the weekend before the season starts.
