Feeney handed the visitors a first half lead when, moments before the break, he attempted an ambitious effort which - unfortunately for Celtic - took a deflection off defender Ciaran Donaghy before spinning beyond the reach of Alex Spackman.

Then, on 77 minutes, Keegan doubled Newry's advantage when he lifted the ball over the advancing keeper.
