United travelled to Newtownabbey to take on an 18th Newtownabbey side that has been performing well this season and whose ranks include a number of former Irish League stars.
The United line-up included a full debut for teenager Corey Fitzpatrick and what an outstanding showing he put in.
Aaron Cheevers gave United the lead however the home team equalised later in the half and could have gone ahead but for the brilliance of keeper Brian McMullan who saved a penalty.
In the second half United had a number of chances to score and should have had a penalty of their own which appeared to be more justifiable than the one awarded against them. As the game was approaching extra time the home team scored a rather fortunate goal to thwart Unitedâ€™s hopes of progressing in the competition.
This week United travel to Rathfern Rangers in a league game.
