Livingston moved up to third place after a goal-less draw against Hamilton on Tuesday night.
The Lions made numerous changes from the starting 11 that lost 3-0 to Accies on Saturday - including a rare start for stand-in goalie Darren Jamieson.
And the goalie was called into actin early on when Gary Fisher's overhead kick almost caught him out, but he tipped over well.
Ross Docherty was red-carded for a rash challenge - minutes after Ziggy Gordon was booked for an equally bad tackle.
And after losing a man, Livi were on the back-foot for most of the match.
Jon McShane and Stevie May missed chances at Accies, while Darren MacKinnon hit the bar.
But Livi held on to leapfrog Falkirk into third.
