Stephen Baxter's side were already assured of a last-eight spot

Chris Morrow headed over for the Crues in the first half while Ciaran Donaghy nodded over a half-chance for Celtic.

DC's CJ McGourty had claims for a penalty just before half-time but referee Stephen Weatherall was unmoved.

The second half was utterly forgettable with DC goalkeeper Declan Browne's tipping away an Eamon McAllister cross the only moment of note.

The game was effectively a dead rubber with Crusaders already guaranteed a quarter-final spot but unable to overhaul group leaders Cliftonville.
