A floodlight failure at the Estadio Jose Alvalade caused a temporary postponement of Tuesday evening's Champions League Group G game between Sporting Lisbon and Maribor.
The first half ended with the hosts leading 2-1, but following the break, both teams were taken off the field after coming out of the changing rooms for the second period.
Following a lengthy pause of about 50 minutes, the lighting issue was resolved, and the game resumed at approximately 9.30pm GMT.
Goals from Mane and Nani gave the Portuguese giants a two-goal lead in the first 45 minutes, but Jefferson's subsequent own goal ensured that the game was delicately poised at the break.
