The visitors came into the match as underdogs following their limited experience in Caf competitions, and they surprised many with their display especially in the first half.
Their Rwandan counterparts could not find the way through the determined Proline who gave as much as they received.
It took the Uganda side just three minutes after the break to find the back of the net. Bright Anukani was cleverly slipped in and he capitalized on the chance by expertly beating the goalkeeper.
The visitors held on until the 87th minute when they conceded a penalty. Coincidentally, it was the 26-year-old Uganda star Farouk Ssentogo who held his nerves to level matters.
