Uprising FC were the better side of the first period, mounting pressure on Abuko United but could not break through their solid defence line despite numerous attempts thus the first half ended goalless.
As action resumed in the second period, Abuko United turned the tie around by putting their opponent under serious pressure thus breaking the deadlock through Sainey Bojang in the 65th minute of the game from a spot-kick.
The win guarantees them a place in the next stage of the competition.
