FALKIRK fell to a single goal in Dundee to fall further off the pace in the Irn-Bru First Division.
The Bairns were beaten by an early header from Craig Forsyth, and had Carl Finnigan red carded, meaning he will miss next week's match with league leaders Raith Rovers.
The Geordie striker walked for punching the ball into the net midway through the second half.
The Bairns had Robert Oljnik to thank for keeping the score down with stunning save from a Gary Harkins fre-kick in the first half and a good gather from Tam Brighton in the second.
Steven Pressley said he was again proud of his players and believed his team should have had a first half penalty when Rab Douglas pulled down Mark Millar.
Stewart Murdoch had kept his place in the team after a solid showing against Partick Thistle, and Mark Stewart also returned from injury for the match at Dens Park, which is Falkirk's third defeat in a row.
The Bairns face Raith Rovers at Stark's Park on Saturday.
