Ten-man Livingston snatched a 1-1 draw with Morton in a dramatic finish in the Ladbrokes Championship.Morton's Scott Tiffoney and Gary Oliver had penalty appeals waved away in a goalless first half, with their side needing a sharp double save by Derek Gaston from Josh Mullin and Raffaele De Vita to stay on terms.Livingston's Shaun Byrne collected a second yellow card for a foul on Gary Harkins, who was then booked for simulation in a separate incident.Alexander parried Michael Tidser's effort and Frank Ross fired over as Morton went in search of a winner - which looked to have arrived with two minutes left when Tiffoney's cross was not cleared and Oliver pounced.There was still time for another twist, however, as Livi's Jackson Longridge blasted home from 20 yards deep into stoppage time.
