Quarter-finals
The four teams who won both their first and second round matches were drawn against the four winners from the Round 3 "qualifiers".
The draw for the quarter-finals was originally supposed to occur after the last third round game (Ballinascreen versus Ballinderry) at Bellaghy. However the draw could not take place because of Lavey's draw with Eoghan Rua. Teams who have already met earlier in the championship could not be paired with each other again in the quarter-finals - the number of such permutations meant the draw was delayed until after the Lavey versus Eoghan Rua replay at Glenullin.
The Round 3 replay and delayed draw also led to the quarter-finals being postponed for a week. They were originally intended to be played a week after the third round, but the delayed draw meant teams would not know their opponents until Wednesday 12 August, which did not give them sufficient notice to play that weekend.
The Ballinderry versus Glenullin match was billed beforehand as tie of the round, and the game everyone wanted to see in the final. It did not disappoint. It was described as "one of the best games seen in this county for years". An Lúb beat Newbridge in a "dogged" encounter, while Bellaghy survived a late Magherafelt comeback to secure their place in the semis. The Dungiven and Eoghan Rua game was supposed to take place on 23 August at 2.00pm at Foreglen. However, before throw-in the game was postponed due to a water-logged pitch. It was rescheduled for two days later in Celtic Park. Dungiven won the game by six points.
