CRUSADERS inflicted a rare defeat upon Coleraine to progress to the last four of the JJB Sports Irish Cup.
The Crues might have moved in front on 24 minutes through Timmy Adamson who tested Michael Doherty with an excellent effort from the edge of the area.
But the visitors did make the breakthrough nine minutes from the interval with a Chris Morrow near post header into the bottom corner from a Stuart Dallas delivery.
After the break the Bannsiders pushed forward in search of an equaliser, perhaps coming closest when substitute Paul Owens saw a free-kick tipped over the bar by 'keeper Sean O'Neill.
The issue was put beyond doubt, however, three minutes into stoppage time when Adamson laid the ball off for Matthew Snoddy to fire home the second for the Crues.
Stephen Baxter's side now face either Dungannon Swifts or Donegal Celtic in the semi-finals.
