Substitute Davie O'Connor struck late as bottom club Drogheda United ruined Paul Doolin’s return to United Park by taking all three points.

The Boynesiders led from the ninth minute when James Chambers' corner was headed decisively past Dan Connor by centre-half Conor Kenna.

Dan Murray volleyed against the Drogheda bar in the second half, but looked to have put Cork back on track when he tapped home after keeper Paul Skinner had saved Guntars Silagailis' header.

However, Alan Mathews' men were rewarded for a superb display in the 80th minute when O'Connor drilled home after Jamie Duffy's cross bounced fortunately into his path.
