Shell-shocked Airdrie boss Rhys McCabe insists their capitulation from 3-0 up should never have been allowed to happen, as 10-man Diamonds blew the chance to stun League One leaders Dunfermline.
McCabe’s men produced a blistering opening 50 minutes at New Broomfield and looked on course to demolish Dunfermline thanks to goals from Gabby McGill, Calum Gallagher and a Robbie Mahon own goal.
But the game turned on a controversial sending off for striker Callum Smith, who was judged to have deliberately handled the ball in the box and denied Dunfermline a clear goal-scoring opportunity.
