That was how it stood at the break but twelve minutes after the restart, with the visitors adopting a 2-4-4 formation, the Dons levelled when a Richard Foster pass over the top found Darren MACKIE who beat Michael Fraser with a low drive.
With time running out and a share of the spoils looking certain, Aberdeen forced a corner. Chris Maguire found Mackie at the near post and he nodded the ball to CONSIDINE who headed home from close range to seal the points.
The win was vital for the Dons as Celtic kept the pressure on at the top of the league with a 4-2 win over Hearts.
