Chesterfield have confirmed a friendly against Leeds United at the Proact Stadium on July 26.
The fixture will kick-off at 3pm, meaning the friendly against Alfreton Town - which had originally been scheduled for the same date - will be brought forward to Tuesday, July 15.
Paul Cook’s side last faced the Whites in the opening round of the Capital One Cup at Elland Road last season, where the Championship outfit eventually prevailed 2-1 after the Spireites took the lead.
The Leeds game will be the first of Chesterfield’s two home friendlies scheduled to take place before the Sky Bet League One campaign.
The Spireites also face Aston Villa on Wednesday, July 30.
