Bhoys head for a replay
A pulsating match which saw a stack of chances and excellent goal-keeping at either end looked to be heading towards a goal-less draw until the 79th minute, when Dons midfielder Jeffrey de Visscher linked with Lee Miller at the edge of the box before driving low past Hoops goalkeeper Artur Boruc.
The Dons were looking forward to the semi-final meeting with Irn-Bru First Division side Queen of the South next month, but in the second minute of injury time Vennegoor of Hesselink threw himself at a cross from substitute Georgios Samaras to force the ball over the line from a couple of yards out.
