Aberdeen striker Darren Mackie's 69th-minute strike against the run of play sent Celtic crashing out of the Scottish Cup as their quarter-final replay at Parkhead finished 1-0.

After being under pressure for most of the game, with their first attempt on goal after the break Mackie fired past Artur Boruc from 12 yards out.

Celtic had equalised late into injury time in the first game but this time the Dons held firm to set up a semi-final meeting with Queen of the South on the weekend of April 12th/13th.

But Dons manager Jimmy Calderwood will wonder how his side managed to leave Parkhead with their goal intact while Celtic boss Gordon Strachan will reflect on the jeers of the Hoops fans at the final whistle.

In the 69th minute the Dons dramatically stole the lead with their first attempt on goal of the second half.

After a rare spell of pressure Celtic failed to clear their lines and, in a busy penalty area, Dons striker Lee Miller flicked the ball through to the unmarked Mackie, who rifled the ball past Boruc from about 12 yards out.

St Mirren were swept aside at Love Street as Scottish One side St Johnstone cruised into the last four of the Scottish Cup.

Rocco Quinn, Andy Jackson and Peter MacDonald helped themselves to a goal apiece in tonight's replay to secure a comfortable win for the Irn-Bru First Division side.

Even an unsuccessful penalty from Paul Sheerin - and a successful one from Billy Mehmet - could not take the gloss off a victory that sets up a meeting with Rangers or Partick Thistle in the next round.
