Livi hold Accies in stalemate
Livingston are up to third after they managed a goalless draw against Hamilton despite playing more than an hour with 10 men.
Ross Docherty, who only entered the game as an 11th-minute substitute, was shown a straight red card in the 27th minute after a reckless lunge on Ziggy Gordon.
It left Richie Burke's side on the defensive for the rest of the game, against a side who had comfortably beaten them 3-0 at the weekend.
The visitors almost took advantage of their numerical superiority immediately as first Gary Fisher forced a good save out of Darren Jamieson and, from the resulting corner, Darian Mackinnon headed against the crossbar.
Steven May, who scored a hat-trick on Saturday, fired wide from a well-worked set-piece in the second period, but the Accies could not find the winner and their four-match winning run came to an end.
