Hearts' difficult summer continued as they squandered a lead, conceding two late goals to lose 2-1 to Aberdeen. The Jambos had taken the lead through Oisin McEntee's first-half goal but were denied a much-needed victory. Lewis Mayo equalized in the 90th minute, and Kevin Nisbet scored a stoppage-time penalty after Stuart Findlay was sent off.
This loss marked a third consecutive defeat for Wouter Vrancken. Aberdeen boss Stephen Robinson had given Chris Cadden his debut, and the Dons built on their momentum from the Premier Sports Cup.
Hearts made five changes to their side, including debuts for goalkeeper Beau Reus and Laurent Mendy. The match was marked by protests from the 1,600-strong travelling support, who sang anti-Scottish Football Association songs. Following a summer of transition and a disappointing Champions League qualifier, Hearts' fans were anxious about the new season. The Jambos' makeshift defense looked vulnerable, but they took the lead in the 35th minute through McEntee's goal.
Aberdeen levelled in the 90th minute, and Nisbet's stoppage-time penalty sealed the win.
