A last-gasp point deep in the bowels of extra-time saw Derry and Ulster club champions Slaughtneil just manage to survive against a fiercely committed O'Donovan Rossa (Magherafelt) in a riveting county championship tie last night.
Slaughtneil's total of 1-16, their goal came from Paul Bradley, was matched by Rossa's 0-19 after the sides had been level at half-time (1-6 to 0-9) and again at the end of normal time (1-15 to 0-18).
The Heavrons Shane and Danny shared the bulk of the Rossa scores and appeared to have taken their side to victory until Christopher Bradley converted a long-distance free with the last kick of the game to ensure stalemate.
Damien Barton's finely-tuned Kilrea side beat Dungiven (1-10 to 0-12), while Lavey swept past Loup (4-7 to 2-8) and Swatragh pipped Newbridge (2-6 to 1-8).
Pearse Og booked an intimidating quarter-final meeting with perennial champions Crossmaglen Rangers in the Armagh senior football championship championship when they beat Dromintee by 2-12 to 1-5.
The other Armagh quarter-finals are Harps v Killeavy, Annaghmore v Ballymacnab and Granemore v Maghery.
In the Down championship, Ballyholland Harps created an upset when they just managed to edge out fancied Clonduff by 2-11 to 1-13. The match-winning goal was scored by wing-back Joe Murphy deep in injury-time.
Liatroim Fontenoys also provided a shock when they overcame Bryansford by 3-11 to 0-16 while Castlewellan proved superior to Longstone by 3-15 to 1-13.
In the Fermanagh championship quarter-final replay, Derrygonnelly were much too strong for Ederney in streaking to a 1-14 to 1-5 win.
Derrygonnelly will now meet Devenish, while Roslea and Erne Gaels will clash in the semi-finals.
And it's a case of how the mighty have fallen in Antrim. St Gall's may have won 13 county titles since 2001, but their reputation counted for nothing against Cargin at the weekend.
Ex-Derry boss John Brennan had the Toome outfit fired up to such an extent that they won a throbbing tussle by 1-14 to 0-9, with the McCann brothers Tomas (0-7) and Michael (0-3) grabbing the lion's share of their scores.
