A terrific headed goal from Gavin Peers booked Sligo Rovers' passage through to the quarter-finals of the FAI Ford Cup as they beat Cork City 1-0 at the Showgrounds.
Drogheda United will join Sligo in Monday evening's draw for the last eight as they came from behind to earn a 3-2 win at Longford Town.
Sligo had the best chance of a poor first half on 28 minutes. Kieran Djilali put Danny North through on goal, but Cork 'keeper Mark McNulty make a fine save from the striker's shot.
Cork responded almost immediately with Sligo defender Jeff Henderson doing well to get back and make a last-ditch tackle on Stephen Kenny.
Sligo really upped their game on the resumption and McNulty made a fine save from Raffaele Cretaro before the home side took the lead with what proved their matchwinning goal on 57 minutes.
Central defender Peers rose above everyone in the area to head home a superb cross from man-of-the-match Djilali.
Two goals in as many minutes early in the second half helped Drogheda overcome First Division promotion-chasers Longford at City Calling Stadium.
Longford started positively and were deservedly ahead on 17 minutes.
Drogheda failed to properly defend a corner from Ryan Connolly and central defender Brian McCarthy met the ball at the near post to power a header beyond Michael Schlingermann to the net.
But Drogheda were revitalised in the second half and levelled 10 minutes in with a similar goal as a David Cassidy corner was headed home by midfielder Paul O'Conor.
Scarcely a minute elapsed when Mick Cooke's side were in front. Declan O'Brien headed down a Mick Daly cross and the ball broke for left-back Shane Grimes whose shot was deflected past Town keeper Chris Bennion.
Drogheda added a third goal on 73 minutes. A shot from Grimes was diverted into the path of midfielder Cathal Brady who was presented with a simple tap-in.
Derek O'Brien pulled a goal back for Longford in the first minute of stoppage time with a deflected shot.
Longford then threw everyone up for a corner a minute later which Drogheda safely defended to go through.
