The New Zealand striker was dismissed for violent conduct by Collum, having been bizarrely adjudged to haved elbowed Dorin Goian late on in the fixture.
Cheat Goian did not help the situation bu crumbling in a heap in a disgraceful attempt to get Fallon sent off - which the dire Collum duly obliged him.
Under the Scottish FA’s disciplinary rules, Fallon faced an automatic two-match ban for the offence, but this is reduced to a single-game ban which will take effect during next Monday's game with St Johnstone.
It is not thought that Collum will face any dicsiplinary action despite this obvious error plus his failure to send off Steven Naismith for a studs-up assault on Aberdeen midfielder Rob Milsom which ironically left the perpetrator with a serious knee injury.
