Crusaders will go into the second leg of their Setanta Cup quarter-final at home to Cork 1-0 down after conceding a late goal at Turner's Cross on Tuesday.
Danny Morrissey headed in the only goal at the far post in the 89th minute after Adam Rundle had delivered the cross from a short corner move.
Before the goal, David McMaster forced a superb save from Mark McNulty after the home keeper's poor clearance.
In the first half, Crues winger Paul Heatley shot just wide.
Then, when Heatley played through to Jordan Owens, City centre-half Dan Murray made a timely challenge.
Just before Morrisey's goal, Cork's Ian Turner had sent a glancing header just wide from Danny Murphy cross.
Crusaders were understrength for this game because of injuries and suspensions.
So boss Stephen Baxter will feel the Crues will have every chance of overturning the deficit in the second leg at Seaview on Monday
