Airdrie won promotion to the Championship with a dramatic 6-5 penalty shoot-out win over Hamilton at New Douglas Park.
The sides couldn't be separated after 120 minutes of football, but when Josh Rae saved Dan O'Reilly's penalty, it meant that Cammy Ballantyne's spot-kick won it for the Diamonds 6-5.
It looked like sub Jean-Pierre Tiehi had won the game for Hamilton after blasting in from close range in 80 minutes, but Gabby McGill levelled the tie on aggregate as he slammed in a last-gasp goal to hand Airdrie a lifeline.
