Holders Rathfriland Rangers continued their defence of the McComb's Coach Travel Intermediate Cup with victory over Oxford Sunnyside at Knockramer Park.
Rathfriland came within moments of being eliminated only to grab last gasp equaliser and then seal the game in extra-time.
Oxford had held the advantage for most of the game after Kevin McAlinden had fired them in front after half-an-hour, but a Dalton Tate header a couple of minutes into stoppage time saw Rangers handed a reprieve.
Jordan Hayes then popped up in the 100th minute after finding himself some space in the home defence to bag what proved to be the winner.
Rangers will be joined in the last eight by St. Oliver Plunkett, Holywood, Donegal Celtic, East Belfast, Rosemount Rec., Crumlin Star and Banbridge Town.
Town were the only NIFL Premier Intermediate League to make the cut. They also had to come from behind to get past Shankill United at The Hammer.
Mark Marshall had opened the scoring on 41 minutes after connecting with a corner but Stephen McCavitt levelled for Banbridge from the spot deep into first half stoppage time. That was how it stayed until four minutes from time when Adam Hamilton tucked the winner away at the back post.
Oxford Sunnyside v. Rathfriland Rangers
Last season's losing finalists Armagh City fell at home to Rosemount Rec.
The Eagles moved in front on 14 minutes through Stefan Lavery but Reece Ritchie brought the visitors back into it a short time later. It took another late goal, this time on 90 minutes, to settle the tie after Nicholas Eccles turned the ball home to secure a quarter-final berth.
Dollingstown went down by three goals at Planters Park to Crumlin Star. James Doyle needed just three minutes to open the scoring, Kevin Lynch doubled up just over ten minutes after that before Doyle struck again midway through the second half.
East Belfast also accounted for PIL opposition with a two-goal defeat of Limavady United at East Park. Stephen Cockcroft broke the deadlock midway through the first half with Gary McBride adding the second 50 minutes later.
Donegal Celtic got past Islandmagee by the same scoreline. The Hoops raced into a second minute lead thanks to Odhran Craig, with Conor Glenholmes hitting number two with ten minutes of the first half remaining.
St. Oliver Plunkett were the top scorers on the day. They hit five goals past Mossley at Celtic Park, coming from behind through Stephen O'Neill shortly after falling behind to a Timothy Adamson strike.
Goals from Eugene Reid and Sean Jackson either side of the hour put Celtic firmly in the driving seat although Bobbie Crowe did reduce the deficit not long after that. Two late goals Mark Sloan settled the tie, however, to see the West Belfast side safely through.
Holywood complete the quarter-final line-up thanks to a narrow defeat of Newtowne. Calum James hit the only goal of the game just before the half-hour mark.
